Examples with TestConstructor org.springframework.test.context.TestConstructor used on opensource projects

Example 1 with TestConstructor

use of org.springframework.test.context.TestConstructor in project spring-framework by spring-projects.

the class TestConstructorUtils method isAutowirableConstructor.

/**
 * Determine if the supplied constructor for the given test class is
 * autowirable.
 *
 * <p>A constructor is considered to be autowirable if one of the following
 * conditions is {@code true}.
 *
 * <ol>
 * <li>The constructor is annotated with {@link Autowired @Autowired}.</li>
 * <li>{@link TestConstructor @TestConstructor} is <em>present</em> or
 * <em>meta-present</em> on the test class with
 * {@link TestConstructor#autowireMode() autowireMode} set to
 * {@link AutowireMode#ALL ALL}.</li>
 * <li>The default <em>test constructor autowire mode</em> has been set to
 * {@code ALL} in {@link SpringProperties} or in the supplied fallback
 * {@link PropertyProvider} (see
 * {@link TestConstructor#TEST_CONSTRUCTOR_AUTOWIRE_MODE_PROPERTY_NAME}).</li>
 * </ol>
 * @param constructor a constructor for the test class
 * @param testClass the test class
 * @param fallbackPropertyProvider fallback property provider used to look up
 * the value for the default <em>test constructor autowire mode</em> if no
 * such value is found in {@link SpringProperties}
 * @return {@code true} if the constructor is autowirable
 * @since 5.3

Example 2 with TestConstructor

use of org.springframework.test.context.TestConstructor in project spring-framework by spring-projects.

the class SpringExtension method supportsParameter.

/**
 * Determine if the value for the {@link Parameter} in the supplied {@link ParameterContext}
 * should be autowired from the test's {@link ApplicationContext}.
 * <p>A parameter is considered to be autowirable if one of the following
 * conditions is {@code true}.
 * <ol>
 * <li>The {@linkplain ParameterContext#getDeclaringExecutable() declaring
 * executable} is a {@link Constructor} and
 * {@link TestConstructorUtils#isAutowirableConstructor(Constructor, Class, PropertyProvider)}
 * returns {@code true}. Note that {@code isAutowirableConstructor()} will be
 * invoked with a fallback {@link PropertyProvider} that delegates its lookup
 * to {@link ExtensionContext#getConfigurationParameter(String)}.</li>
 * <li>The parameter is of type {@link ApplicationContext} or a sub-type thereof.</li>
 * <li>The parameter is of type {@link ApplicationEvents} or a sub-type thereof.</li>
 * <li>{@link ParameterResolutionDelegate#isAutowirable} returns {@code true}.</li>
 * </ol>
 * <p><strong>WARNING</strong>: If a test class {@code Constructor} is annotated
 * with {@code @Autowired} or automatically autowirable (see {@link TestConstructor}),
 * Spring will assume the responsibility for resolving all parameters in the
 * constructor. Consequently, no other registered {@link ParameterResolver}
 * will be able to resolve parameters.
 * @see #resolveParameter
 * @see TestConstructorUtils#isAutowirableConstructor(Constructor, Class)
 * @see ParameterResolutionDelegate#isAutowirable
