All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`beforeTestMethod(TestContext testContext)`	If the `REINJECT_DEPENDENCIES_ATTRIBUTE` in the supplied `test context` has a value of `Boolean.TRUE`, this method will have the same effect as `prepareTestInstance()`; otherwise, this method will have no effect.
`int`	`getOrder()`	Returns `2000`.
`protected void`	`injectDependencies(TestContext testContext)`	Performs dependency injection and bean initialization for the supplied `TestContext` as described in `prepareTestInstance()`.
`void`	`prepareTestInstance(TestContext testContext)`	Performs dependency injection on the `test instance` of the supplied `test context` by `autowiring` and `initializing` the test instance via its own `application context` (without checking dependencies).

- Field Detail
  - REINJECT_DEPENDENCIES_ATTRIBUTE
```
public static final String REINJECT_DEPENDENCIES_ATTRIBUTE
```
    Attribute name for a TestContext attribute which indicates whether or not the dependencies of a test instance should be reinjected in beforeTestMethod(). Note that dependencies will be injected in prepareTestInstance() in any case.
    Clients of a TestContext (e.g., other TestExecutionListeners) may therefore choose to set this attribute to signal that dependencies should be reinjected between execution of individual test methods.
    Permissible values include Boolean.TRUE and Boolean.FALSE.

  - getOrder
```
public final int getOrder()
```
    Returns 2000.
    Specified by:
    getOrder in interface Ordered
    Overrides:
    getOrder in class AbstractTestExecutionListener
    Returns:
    the order value

  - prepareTestInstance
```
public void prepareTestInstance(TestContext testContext)
                         throws Exception
```
    Performs dependency injection on the test instance of the supplied test context by autowiring and initializing the test instance via its own application context (without checking dependencies).
    The REINJECT_DEPENDENCIES_ATTRIBUTE will be subsequently removed from the test context, regardless of its value.
    Specified by:
    prepareTestInstance in interface TestExecutionListener
    Overrides:
    prepareTestInstance in class AbstractTestExecutionListener
    Parameters:
    testContext - the test context for the test; never null
    Throws:
    Exception - allows any exception to propagate
  - beforeTestMethod
```
public void beforeTestMethod(TestContext testContext)
                      throws Exception
```
    If the REINJECT_DEPENDENCIES_ATTRIBUTE in the supplied test context has a value of Boolean.TRUE, this method will have the same effect as prepareTestInstance(); otherwise, this method will have no effect.
    Specified by:
    beforeTestMethod in interface TestExecutionListener
    Overrides:
    beforeTestMethod in class AbstractTestExecutionListener
    Parameters:
    testContext - the test context in which the test method will be executed; never null
    Throws:
    Exception - allows any exception to propagate
  - injectDependencies
```
protected void injectDependencies(TestContext testContext)
                           throws Exception
```
    Performs dependency injection and bean initialization for the supplied TestContext as described in prepareTestInstance().
    The REINJECT_DEPENDENCIES_ATTRIBUTE will be subsequently removed from the test context, regardless of its value.
    Parameters:
    testContext - the test context for which dependency injection should be performed (never null)
    Throws:
    Exception - allows any exception to propagate
    See Also:
    prepareTestInstance(TestContext), beforeTestMethod(TestContext)
