Sam Brannen f9523a785b Support @⁠MockitoBean and @⁠MockitoSpyBean on test constructor parameters Prior to this commit, @⁠MockitoBean and @⁠MockitoSpyBean could be declared on fields or at the type level (on test classes and test interfaces), but not on constructor parameters. Consequently, a test class could not use constructor injection for bean overrides. To address that, this commit introduces support for @⁠MockitoBean and @⁠MockitoSpyBean on constructor parameters in JUnit Jupiter test classes. Specifically, the Bean Override infrastructure has been overhauled to support constructor parameters as declaration sites and injection points alongside fields, and the SpringExtension now recognizes composed @⁠BeanOverride annotations on constructor parameters in supportsParameter() and resolves them properly in resolveParameter(). Note, however, that this support has not been introduced for @⁠TestBean. For example, the following which uses field injection: @⁠SpringJUnitConfig(TestConfig.class) class BeanOverrideTests { @⁠MockitoBean CustomService customService; // tests... } Can now be rewritten to use constructor injection: @⁠SpringJUnitConfig(TestConfig.class) class BeanOverrideTests { private final CustomService customService; BeanOverrideTests(@⁠MockitoBean CustomService customService) { this.customService = customService; } // tests... } With Kotlin this can be achieved even more succinctly via a compact constructor declaration: @⁠SpringJUnitConfig(TestConfig::class) class BeanOverrideTests(@⁠MockitoBean val customService: CustomService) { // tests... } Of course, if one is a fan of so-called "test records", that can also be achieved succinctly with a Java record: @⁠SpringJUnitConfig(TestConfig.class) record BeanOverrideTests(@⁠MockitoBean CustomService customService) { // tests... } Closes gh-36096		1 day ago
