This commit improves `TestCompiler` with a `with` function that allows
to customize a test compiler instance. Rather than `TestCompiler`
knowing about `TestGenerationContext`, the latter implements the
function so that it can be passed as is.

Update `TestCompiler` so that it can access and generate resources.
This change will allow the `TestCompiler` to be used with annotation
processor tests that generate resources.

Update `TestCompiler` so that it can now load cglib generated classes.
This commit adds support to `DynamicJavaFileManager` so that it can
reference generated classes and adds a new lookup function to
`CompileWithTargetClassAccessClassLoader` to that it can load the
bytecode of generated classes directly.

Previously, the generated classes from an InMemoryGeneratedFiles were
not taken into account and if generated code refers to any of them,
compilation failed.
This commit introduces a ClasFile abstraction, similar to ResourceFile
for resources that represents an existing generated class.

Previously, a shortcut method for the default ExecutableMode was
provided, but we found out that the shortcut makes it harder to
determine the intent.
This commit harmonizes hints registration for types, methods, and
fields. An ExecutableMode is now mandatory to register a method or
constructor. Previous methods that infer a mode or provided a
customizer of the builder are deprecated.
Closes gh-29135
Prior to this commit, the `RuntimeHintsAgent` and its testing
infrastructure would assume that calling `MyClass.class.getMethods()`
requires a reflection hint on the class for introspecting public/private
methods.
GraalVM does not require this, in fact this call only returns methods
that have reflection hints in the native image.
This commit refines the agent behavior for `Class.getMethods()`,
`Class.getDeclaredMethods()`, `Class.getFields()` and
`Class.getDeclaredFields()`. With this change, registering at least one
method/field for reflection is enough to match.
During the execution of Java tests, all methods and fields will be
provided, regardless of hints being registered or not. This could cause
false negatives where we're missing reflection hints on methods or
fields.
This risk is mitigated thanks to additional instrumentation on
`Method.getAnnotations()`, `Method.getParameterTypes()` and
`Method.invoke()`. If a method is found reflectively, chances are it
will be used for further reflection.
Closes gh-29091
Prior to this commit, if the TypeReference supplied to
ResourceHintsPredicates.forResource(TypeReference,String) was for a
class declared in the default package (i.e., without a package), the
resolveAbsoluteResourceName() method incorrectly prepended two leading
slashes (//) to the absolute resource name, causing correct matches to
fail.
This commit fixes this by adding special handling for a TypeReference
without a package name. In addition, this commit introduces lenient
handling of resource names by consistently removing a leading slash in
ResourceHintsPredicates.forResource(*) methods. The latter aligns with
absolute resource path handling in other places in the framework, such
as ClassPathResource.
Closes gh-29086
This commit harmonizes the package space by moving the TestCompiler
infrastructure from the now outdated "generator" package to "generate".
Closes gh-29082
Previously, com.thoughtworks.qdox:qdox was declared as an api
dependency of spring-core-test despite it only being used in the
module's internals. This resulted in it unnecessarily appearing on the
compile classpath of consuming projects.
This commit moves qdox to be an implementation dependency, removing it
from the compile classpath of consuming projects but ensuring that it's
still available at runtime.
Closes gh-29066
Prior to this commit, the `RuntimeHintsAgent` would instrument
`Method.invoke` in a way that fails when invoked methods are not public.
This commit ensures that before delegating the invocation call, the
instrumentation makes the method accessible before delegating the call.
Fixes gh-29046
This commit adapts the registration of fields, constructors, and methods
to provide the same convenience than the reflection-based one available
in ReflectionHints.
See gh-29011
This commit harmonizes the registration of an executable so that
the default method and the method that takes an empty customizer
produces the same hint. The same applies to the readable flag of
a field hint.
Rather than returning a list of executable modes, the "highest" mode
is retained.
See gh-29011
Based on the feedback in #28977 an easy way to create a list of
type references based on a vararg of classes is helpful when
registering the same hints for several types.
This commit fixes `RecordedInvocation` and
`RuntimeHintsInvocationsAssert` so that they don't refer to the recorded
instance for static calls.
This also consistently resolves the `TypeReference` of recorded
instances.
Fixes gh-28907
CompileWithTargetClassAccessClassLoader is currently only used within the
CompileWithTargetClassAccessExtension which is dedicated to JUnit Jupiter
support which in turn should not have any direct dependencies on Hamcrest.
In other words, the JupiterTestEngine should not load any Hamcrest types
that would cause issues with the CompileWithTargetClassAccessClassLoader.
Prior to this commit, CompileWithTargetClassAccessExtension failed to
properly select overloaded test methods because it ignored the method
parameter list when looking up the test method.
This commit addresses this issue by selecting the test method using its
fully qualified method name which takes in account the class name,
method name, and parameter names.
Closes gh-28901
Commit 9dd7f5412a (which has now been
reverted) addressed the issue of having the TestNG TestEngine for the
JUnit Platform on the test runtime classpath by allowing `org.testng`
types to pass through to the original ClassLoader; however, that fix
merely obfuscated the underlying issue.
The underlying issue is that the CompileWithTargetClassAccessExtension
is only applicable to JUnit Jupiter tests and therefore should launch
the JUnit Platform with only the JUnit Jupiter TestEngine active.
This commit addresses this issue by applying an EngineFilter to include
only the "junit-jupiter" test engine.
Closes gh-28900
Since the RuntimeHintsAgentCondition is based solely on the result of
invoking a boolean static method, there is no need to implement a custom
ExecutionCondition. For such use cases, the @EnabledIf support in JUnit
Jupiter is sufficient.
This commit therefore replaces the custom RuntimeHintsAgentCondition
with use of @EnabledIf as a meta-annotation.
