Introduce support for HtmlUnit in Spring MVC Test 

This commit introduces integration between MockMvc and HtmlUnit, thus
simplifying end-to-end testing when using HTML-based views and enabling
developers to do the following.

 - Easily test HTML pages using tools such as HtmlUnit, WebDriver, & Geb
   without the need to deploy to a Servlet container

 - Test JavaScript within pages

 - Optionally test using mock services to speed up testing

 - Share logic between in-container, end-to-end tests and
   out-of-container integration tests

==== HtmlUnit Integration
Spring provides integration between <<spring-mvc-test-server,MockMvc>> and
http://htmlunit.sourceforge.net/[HtmlUnit]. This simplifies performing end to end testing
when using HTML based views. This integration enables developers to:
* Easily test pages using tools (i.e. http://htmlunit.sourceforge.net/[HtmlUnit],
http://seleniumhq.org/projects/webdriver/[WebDriver], &
http://www.gebish.org/manual/current/testing.html#spock_junit__testng[Geb]) that we
already use for integration testing without starting an application server
* Support testing of JavaScript
* Optionally test using mock services to speed up testing.
* Share logic between end-to-end tests and integration tests
[NOTE]
====
MockMvc will work with templating technologies that do not rely on a Servlet Container
(i.e. Thymeleaf, Freemarker, Velocity, etc). It does not work with JSPs since they rely on
the Servlet Container.
====
[[spring-mvc-test-server-htmlunit-why]]
===== Why HtmlUnit Integration?
The most obvious question that comes to mind is "Why do I need this?" The answer is best
found by exploring a very basic sample application. Assume you have a Spring MVC web
application that allows CRUD operations on a `Message` object. The application also allows
paging through all messages. How would you go about testing it?
With Spring MVC Test, we can easily test if we are able to create a `Message`.
[source,java]
----
MockHttpServletRequestBuilder createMessage = post("/messages/")
.param("summary", "Spring Rocks")
.param("text", "In case you didn't know, Spring Rocks!");
mockMvc.perform(createMessage)
.andExpect(status().is3xxRedirection())
.andExpect(redirectedUrl("/messages/123"));
----
What if we want to test our form view that allows us to create the message? For example,
assume our form looks like the following snippet:
[source,xml]
----
<form id="messageForm" action="/messages/" method="post">
<div class="pull-right"><a href="/messages/">Messages</a></div>
<label for="summary">Summary</label>
<input type="text" class="required" id="summary" name="summary" value="" />
<label for="text">Message</label>
<textarea id="text" name="text"></textarea>
<div class="form-actions">
<input type="submit" value="Create" />
</div>
</form>
----
How do we ensure that our form will produce the correct request to create a new message? A
naive attempt would look like this:
[source,java]
----
mockMvc.perform(get("/messages/form"))
.andExpect(xpath("//input[@name='summary']").exists())
.andExpect(xpath("//textarea[@name='text']").exists());
----
This test has some obvious problems. If we updated our controller to use the parameter
"message" instead of "text", our test would would incorrectly pass. To resolve this we
could combine our two tests:
[[spring-mvc-test-server-htmlunit-mock-mvc-test]]
[source,java]
----
String summaryParamName = "summary";
String textParamName = "text";
mockMvc.perform(get("/messages/form"))
.andExpect(xpath("//input[@name='" + summaryParamName + "']").exists())
.andExpect(xpath("//textarea[@name='" + textParamName + "']").exists());
MockHttpServletRequestBuilder createMessage = post("/messages/")
.param(summaryParamName, "Spring Rocks")
.param(textParamName, "In case you didn't know, Spring Rocks!");
mockMvc.perform(createMessage)
.andExpect(status().is3xxRedirection())
.andExpect(redirectedUrl("/messages/123"));
----
This would reduce the risk of our test incorrectly passing, but there are still some
problems:
* What if we had multiple forms on our page? Admittedly we could update our xpath
expressions, but they get more complicated the more factors we take into account (are the
fields the correct type, are the fields enabled, etc).
* Another issue is that we are doing double the work we would expect.
We must first verify the view and then we submit the view with the same parameters we just
verified.
Ideally this could be done all at once.
* Last, there are some things that we still cannot account for. For example, what if the
form has JavaScript validation that we wish to validate too?
The overall problem is that testing a web page is not a single interaction. Instead, it is
a combination of how the user interacts with a web page and how that web page interacts
with other resources. For example, the result of form view is used as an input to a user
for creating a message. Another example is that our form view utilizes additional
resources, like JavaScript validation, that impact the behavior of the page.
[[spring-mvc-test-server-htmlunit-why-integration]]
====== Integration testing to the rescue?
To resolve the issues above we could perform integration testing, but this has some
obvious drawbacks. Consider testing the view that allows us to page through the messages.
We might need the following tests:
* Does our page display a message to the user indicating that no results are available
when the messages are empty?
* Does our page properly display a single message?
* Does our page properly support paging?
To set these tests up we would need to ensure our database contained the proper messages
in it. This leads to a number of problems:
* Ensuring the proper messages are in the database can be tedious (think possible foreign
keys).
* Testing would be slow since each test would require ensuring the database was in the
correct state.
* Since our database needs to be in a specific state, we cannot run the test in parallel.
* Assertions on things like auto generated ids, timestamps, etc can be challenging.
These problems do not mean that we should abandon integration testing all together.
Instead, we can reduce the number of integration tests by moving our detailed tests to use
mock services which will perform much faster. We can then use fewer integration tests that
validate simple workflows to ensure that everything works together properly.
[[spring-mvc-test-server-htmlunit-why-mockmvc]]
====== Enter HtmlUnit Integration
So how can we provide a balance between testing the interactions of our pages and still
get performance? I'm sure you already guessed it...integrating with HtmlUnit
will allow us to:
* Easily test our pages using tools (i.e. HtmlUnit, WebDriver, & Geb) that we already use
for integration testing without starting an application server
* Support testing of JavaScript
* Optionally test using mock services to speed up testing.
* Share logic between end-to-end tests and integration tests
[[spring-mvc-test-server-htmlunit-options]]
====== HtmlUnit Integration Options
There are a number of ways to integrate with HtmlUnit. You can find a summary below:
* <<spring-mvc-test-server-htmlunit-mah,MockMvc and HtmlUnit>> - Use this option if you want the raw libraries
* <<spring-mvc-test-server-htmlunit-webdriver,MockMvc and WebDriver>> - Use this option to ease development and be able to reuse code
between integration and end-to-end testing.
* <<spring-mvc-test-server-htmlunit-geb,MockMvc and Geb>> - Use this option if you like using Groovy for testing, would like to
ease development, and be able to reuse code between integration and end-to-end testing.
[[spring-mvc-test-server-htmlunit-mah]]
===== MockMvc and HtmlUnit
This section describes how to integrate `MockMvc` and HtmlUnit. Use this option if you
want to use the raw HtmlUnit libraries.
[[spring-mvc-test-server-htmlunit-mah-setup]]
====== MockMvc and HtmlUnit Setup
We can easily create an HtmlUnit `WebClient` that integrates with `MockMvc` using the
following:
[source,java]
----
@Autowired
WebApplicationContext context;
WebClient webClient;
@Before
public void setup() {
webClient = MockMvcWebClientBuilder
.webAppContextSetup(context)
.createWebClient();
}
----
[NOTE]
====
This is a simple example of using `MockMvcWebClientBuilder`. For advanced usage see
<<Advanced MockMvcWebClientBuilder>>
====
This will ensure any URL that has a host of "localhost" will be directed at our MockMvc
instance without the need for HTTP. Any other URL will be requested as normal. This allows
for easily testing with the use of CDNs.
[[spring-mvc-test-server-htmlunit-mah-usage]]
====== MockMvc and HtmlUnit Usage
Now we can use HtmlUnit as we normally would, but without the need to deploy our
application. For example, we can request the view to create a message with the following:
[source,java]
----
HtmlPage createMsgFormPage = webClient.getPage("http://localhost/messages/form");
----
[NOTE]
====
The the context path is "". Alternatively, we could have specified the context path as
illustrated in <<Advanced MockMvcWebClientBuilder>>.
====
We can then fill out the form and submit it to create a message.
[source,java]
----
HtmlForm form = createMsgFormPage.getHtmlElementById("messageForm");
HtmlTextInput summaryInput = createMsgFormPage.getHtmlElementById("summary");
summaryInput.setValueAttribute("Spring Rocks");
HtmlTextArea textInput = createMsgFormPage.getHtmlElementById("text");
textInput.setText("In case you didn't know, Spring Rocks!");
HtmlSubmitInput submit = form.getOneHtmlElementByAttribute("input", "type", "submit");
HtmlPage newMessagePage = submit.click();
----
Finally, we can verify that a new message was created successfully
[source,java]
----
assertThat(newMessagePage.getUrl().toString()).endsWith("/messages/123");
String id = newMessagePage.getHtmlElementById("id").getTextContent();
assertThat(id).isEqualTo("123");
String summary = newMessagePage.getHtmlElementById("summary").getTextContent();
assertThat(summary).isEqualTo("Spring Rocks");
String text = newMessagePage.getHtmlElementById("text").getTextContent();
assertThat(text).isEqualTo("In case you didn't know, Spring Rocks!");
----
This improves on our <<spring-mvc-test-server-htmlunit-mock-mvc-test,MockMvc test>> in a
number of ways. First we no longer have to explicitly verify our form and then create a
request that looks like the form. Instead, we request the form, fill it out, and submit
it. This reduces the overhead significantly.
Another important factor is that
http://htmlunit.sourceforge.net/javascript.html[HtmlUnit uses Mozilla Rhino engine] to
evaluate JavaScript on your pages. This means, that we can verify our JavaScript methods
as well!
Refer to the http://htmlunit.sourceforge.net/gettingStarted.html[HtmlUnit documentation]
for additional information about using HtmlUnit.
[[spring-mvc-test-server-htmlunit-mah-advanced-builder]]
====== Advanced MockMvcWebClientBuilder
In our example above we used `MockMvcWebClientBuilder` in the simplest way possible.
[source,java]
----
@Autowired
WebApplicationContext context;
WebClient webClient;
@Before
public void setup() {
webClient = MockMvcWebClientBuilder
.webAppContextSetup(context)
.createWebClient();
}
----
We could also specify some optional arguments:
[source,java]
----
@Before
public void setup() {
webClient = MockMvcWebClientBuilder
// demonstrates applying a MockMvcConfigurer (Spring Security)
.webAppContextSetup(context, springSecurity())
// for illustration only - defaults to ""
.contextPath("")
// By default MockMvc is used for localhost only
// the following will use MockMvc for example.com and example.org too
.useMockMvcForHosts("example.com","example.org")
.createWebClient();
}
----
We could also perform the exact same setup using the following:
[source,java]
----
MockMvc mockMvc = MockMvcBuilders
.webAppContextSetup(context)
.build();
webClient = MockMvcWebClientBuilder
.mockMvcSetup(mockMvc)
// for illustration only - defaults to ""
.contextPath("")
// By default MockMvc is used for localhost only
// the following will use MockMvc for example.com and example.org too
.useMockMvcForHosts("example.com","example.org")
.createWebClient();
----
This is more verbose, but by building the `WebClient` with a `MockMvc` instance we have
the full power of `MockMvc` at our finger tips. Ultimately, this is simply performing the
following:
[TIP]
====
For additional information on creating a `MockMvc` instance refer to
<<spring-mvc-test-server-setup-options>>.
====
[[spring-mvc-test-server-htmlunit-webdriver]]
===== MockMvc and WebDriver
In the previous section, we have already seen how to use MockMvc with HtmlUnit.
In this section, we will leverage additional abstractions within
http://docs.seleniumhq.org/projects/webdriver/[WebDriver] to make things even easier.
[[spring-mvc-test-server-htmlunit-webdriver-why]]
====== Why WebDriver and MockMvc?
We can already use HtmlUnit and MockMvc, so why would we want to use WebDriver? WebDriver
provides a very elegant API and allows us to easily organize our code. To better
understand, let's explore an example.
[NOTE]
====
Despite being a part of http://docs.seleniumhq.org/[Selenium], WebDriver does not require
a Selenium Server to run your tests.
====
Suppose we need to ensure that a message is created properly. The tests involve finding
the html inputs, filling them out, and making various assertions.
There are many tests because we want to test error conditions as well. For example, we
want to ensure that if we fill out only part of the form we get an error. If we fill out
the entire form, the newly created message is displayed afterwards.
If one of the fields was named "summary", then we might have something like the following
repeated everywhere within our tests:
[source,java]
----
HtmlTextInput summaryInput = currentPage.getHtmlElementById("summary");
summaryInput.setValueAttribute(summary);
----
So what happens if we change the id to be "smmry".
This means we would have to update all of our tests! Instead we would hope that we wrote a
bit more elegant code where filling out the form was in its own method:
[source,java]
----
public HtmlPage createMessage(HtmlPage currentPage, String summary, String text) {
setSummary(currentPage, summary);
...
}
public void setSummary(HtmlPage currentPage, String summary) {
HtmlTextInput summaryInput = currentPage.getHtmlElementById("summary");
summaryInput.setValueAttribute(summary);
}
----
This ensures that if we change the UI we do not have to update all of our tests.
We might take it a step further and place this logic within an Object that represents the
`HtmlPage` we are currently on.
[source,java]
----
public class CreateMessagePage {
HtmlPage currentPage;
HtmlTextInput summaryInput;
HtmlSubmitInput submit;
public CreateMessagePage(HtmlPage currentPage) {
this.currentPage = currentPage;
this.summaryInput = currentPage.getHtmlElementById("summary");
this.submit = currentPage.getHtmlElementById("submit");
}
public <T> T createMessage(String summary, String text) throws Exception {
setSummary(summary);
HtmlPage result = submit.click();
boolean error = CreateMessagePage.at(result);
return (T) (error ? new CreateMessagePage(result) : new ViewMessagePage(result));
}
public void setSummary(String summary) throws Exception {
summaryInput.setValueAttribute(summary);
}
public static boolean at(HtmlPage page) {
return "Create Message".equals(page.getTitleText());
}
}
----
Formerly, this pattern is known as the
https://code.google.com/p/selenium/wiki/PageObjects[Page Object Pattern]. While we can
certainly do this with HtmlUnit, WebDriver provides some tools that we will explore in the
following sections make this pattern much easier.
[[spring-mvc-test-server-htmlunit-webdriver-setup]]
====== MockMvc and WebDriver Setup
We can easily create a WebDriver implementation that integrates with MockMvc using the
following:
[source,java]
----
@Autowired
WebApplicationContext context;
WebDriver driver;
@Before
public void setup() {
driver = MockMvcHtmlUnitDriverBuilder
.webAppContextSetup(context)
.createDriver();
}
----
[NOTE]
====
This is a simple example of using `MockMvcHtmlUnitDriverBuilder`.
For more advanced usage, refer to <<Advanced MockMvcHtmlUnitDriverBuilder>>
====
This will ensure any URL that has a host of "localhost" will be directed at our MockMvc
instance without the need for HTTP. Any other URL will be requested as normal. This allows
for easily testing with the use of CDNs.
[[spring-mvc-test-server-htmlunit-webdriver-usage]]
====== MockMvc and WebDriver Usage
Now we can use WebDriver as we normally would, but without the need to deploy our
application. For example, we can request the view to create a message with the following:
[source,java]
----
CreateMessagePage page = CreateMessagePage.to(driver);
----
We can then fill out the form and submit it to create a message.
[source,java]
----
ViewMessagePage viewMessagePage =
page.createMessage(ViewMessagePage.class, expectedSummary, expectedText);
----
This improves on the design of our
<<spring-mvc-test-server-htmlunit-mah-usage,HtmlUnit test>> by leveraging the Page Object
Pattern. As we mentioned in <<spring-mvc-test-server-htmlunit-webdriver-why>>, we could
use the Page Object Pattern with HtmlUnit, but it is much easier now. Let's take a look at
our `CreateMessagePage`.
[source,java]
----
public class CreateMessagePage
extends AbstractPage { // <1>
// <2>
private WebElement summary;
private WebElement text;
// <3>
@FindBy(css = "input[type=submit]")
private WebElement submit;
public CreateMessagePage(WebDriver driver) {
super(driver);
}
public <T> T createMessage(Class<T> resultPage, String summary, String details) {
this.summary.sendKeys(summary);
this.text.sendKeys(details);
this.submit.click();
return PageFactory.initElements(driver, resultPage);
}
public static CreateMessagePage to(WebDriver driver) {
driver.get("http://localhost:9990/mail/messages/form");
return PageFactory.initElements(driver, CreateMessagePage.class);
}
}
----
<1> The first thing you will notice is that our `CreateMessagePage` extends the
`AbstractPage`. We won't go over the details of `AbstractPage`, but in summary it contains
all the common functionality of all our pages. For example, if your application has a
navigational bar, global error messages, etc. This logic can be placed in a shared
location.
<2> The next thing you will find is that we have a member variable for each of the parts
of the HTML, `WebElement`, we are interested in. ``WebDriver``'s
https://code.google.com/p/selenium/wiki/PageFactory[PageFactory] allows us to remove a lot
of code from HtmlUnit version of `CreateMessagePage` by automatically resolving each
`WebElement`. The
http://selenium.googlecode.com/git/docs/api/java/org/openqa/selenium/support/PageFactory.html#initElements-org.openqa.selenium.WebDriver-java.lang.Class-[PageFactory#initElements(WebDriver,Class<T>)]
method will automatically resolve each `WebElement` by using the field name and trying to
look it up by id or name of the element on the HTML page.
<3> We can use the
https://code.google.com/p/selenium/wiki/PageFactory#Making_the_Example_Work_Using_Annotations[@FindBy annotation]
to override the default. Our example demonstrates how we can use the `@FindBy` annotation
to lookup our submit button using the css selector of *input[type=submit]*.
Finally, we can verify that a new message was created successfully
[source,java]
----
assertThat(viewMessagePage.getMessage()).isEqualTo(expectedMessage);
assertThat(viewMessagePage.getSuccess()).isEqualTo("Successfully created a new message");
----
We can see that our `ViewMessagePage` can allow us to interact with our custom domain
model. For example, it exposes a method that returns a `Message` object.
[source,java]
----
public Message getMessage() throws ParseException {
Message message = new Message();
message.setId(getId());
message.setCreated(getCreated());
message.setSummary(getSummary());
message.setText(getText());
return message;
}
----
We can then leverage the rich domain objects in our assertions.
Last, don't forget to close the `WebDriver` instance when we are done.
[source,java]
----
@After
public void destroy() {
if(driver != null) {
driver.close();
}
}
----
For additional information on using WebDriver, refer to the
https://code.google.com/p/selenium/wiki/GettingStarted[WebDriver documentation].
[[spring-mvc-test-server-htmlunit-webdriver-advanced-builder]]
====== Advanced MockMvcHtmlUnitDriverBuilder
In our example above we used `MockMvcHtmlUnitDriverBuilder` in the simplest way possible.
[source,java]
----
WebClient webClient;
@Before
public void setup() {
webClient = MockMvcWebClientBuilder
.webAppContextSetup(context)
.createWebClient();
}
----
We could also specify some optional arguments:
[source,java]
----
WebClient webClient;
@Before
public void setup() {
webClient = MockMvcWebClientBuilder
// demonstrates applying a MockMvcConfigurer (Spring Security)
.webAppContextSetup(context, springSecurity())
// for illustration only - defaults to ""
.contextPath("")
// By default MockMvc is used for localhost only
// the following will use MockMvc for example.com and example.org too
.useMockMvcForHosts("example.com","example.org")
.createWebClient();
}
----
We could also perform the exact same setup using the following:
[source,java]
----
MockMvc mockMvc = MockMvcBuilders
.webAppContextSetup(context)
.apply(springSecurity())
.build();
webClient = MockMvcWebClientBuilder
.mockMvcSetup(mockMvc)
// for illustration only - defaults to ""
.contextPath("")
// By default MockMvc is used for localhost only
// the following will use MockMvc for example.com and example.org too
.useMockMvcForHosts("example.com","example.org")
.createWebClient();
----
This is more verbose, but by building the `WebDriver` with a `MockMvc` instance we have
the full power of `MockMvc` at our finger tips. Ultimately, this is simply performing the
following:
[TIP]
====
For additional information on creating a `MockMvc` instance refer to
<<spring-mvc-test-server-setup-options>>.
====
[[spring-mvc-test-server-htmlunit-geb]]
===== MockMvc and Geb
In the previous section, we saw how to use MockMvc with WebDriver.
In this section, we will use http://www.gebish.org/[Geb] to make our tests more Groovy.
[[spring-mvc-test-server-htmlunit-geb-why]]
====== Why Geb and MockMvc?
Geb is backed by WebDriver, so it offers many of the
<<spring-mvc-test-server-htmlunit-webdriver-why,same benefits>> we got from WebDriver.
However, Geb makes things even easier by taking care of some of the boiler plate code for
us.
[[spring-mvc-test-server-htmlunit-geb-setup]]
====== MockMvc and Geb Setup
We can easily initialize Geb with a WebDriver implementation that uses `MockMvc` with the
following:
[source,groovy]
----
def setup() {
browser.driver = MockMvcHtmlUnitDriverBuilder
.webAppContextSetup(context, springSecurity())
.createDriver()
}
----
[NOTE]
====
This is a simple example of using `MockMvcHtmlUnitDriverBuilder`.
For more advanced usage, refer to <<Advanced MockMvcHtmlUnitDriverBuilder>>
====
This will ensure any URL that has a host of "localhost" will be directed at our MockMvc
instance without the need for HTTP. Any other URL will be requested as normal. This allows
for easily testing with the use of CDNs.
[[spring-mvc-test-server-htmlunit-geb-usage]]
====== MockMvc and Geb Usage
Now we can use Geb as we normally would, but without the need to deploy our application.
For example, we can request the view to create a message with the following:
[source,groovy]
----
to CreateMessagePage
----
We can then fill out the form and submit it to create a message.
[source,groovy]
----
when:
form.summary = expectedSummary
form.text = expectedMessage
submit.click(ViewMessagePage)
----
Any unrecognized method calls or property accesses/references that are not found will be
forwarded to the current page object. This removes a lot of the boilerplate code we needed
when using WebDriver directly.
Additionally, this improves on the design of our
<<spring-mvc-test-server-htmlunit-mah-usage,HtmlUnit test>>. The most obvious change is
that we are now using the Page Object Pattern. As we mentioned in
<<spring-mvc-test-server-htmlunit-webdriver-why>>, we could use the Page Object Pattern
with HtmlUnit, but it is much easier now.
Let's take a look at our `CreateMessagePage`.
[source,groovy]
----
class CreateMessagePage extends Page {
static at = { assert title == 'Messages : Create'; true }
static url = 'messages/form'
static content = {
submit { $('input[type=submit]') }
form { $('form') }
errors(required:false) { $('label.error, .alert-error')?.text() }
}
}
----
The first thing you will notice is that our `CreateMessagePage` extends the `Page`.
We won't go over the details of `Page`, but in summary it contains base functionality for all our pages.
The next thing you will notice is that we define a URL in which this page can be found.
This allows us to navigate to the page with:
[source,groovy]
----
to CreateMessagePage
----
We also have a closure that determines if we are at the specified page.
It should return true if we are on the correct page.
This is why we can assert that we are on the correct page with:
[source,groovy]
----
then:
at CreateMessagePage
errors.contains('This field is required.')
----
[NOTE]
====
We use an assertion in the closure, so we can determine where things went wrong if we were
at the wrong page.
====
We last create a content closure that specifies all the areas of interest within the page.
We can use a
http://www.gebish.org/manual/current/intro.html#the_jquery_ish_navigator_api[jQuery-ish Navigator API]
to select the content we are interested in.
Finally, we can verify that a new message was created successfully
[source,groovy]
----
then:
at ViewMessagePage
success == 'Successfully created a new message'
id
date
summary == expectedSummary
message == expectedMessage
----
