我正在尝试将powermock库添加到正在运行的项目中，但出现错误.

I'm trying add the powermock library to the working project, but I'm getting errors.

我如何添加它:

1)AbsTest extends PowerMockTestCase

2)Build.gradle依赖项

2) Build.gradle dependencies

3)在某些测试中，添加@PrepareForTest({SomeClass.class}).完成此步骤后，就会发生此错误.

3) In some test add @PrepareForTest({SomeClass.class}). After this step this error occured.

在build.gradle中包含所有库. 在初始化HeadlessApplication以便使用Gdx.*静态变量的地方发生了错误.

In build.gradle all libraries are included. Error occured in a place where initialize HeadlessApplication for use Gdx.* static vars.

项目中的所有测试都扩展了此类:

All tests in project extend this class:

abstract public class AbsTest extends PowerMockTestCase { static { initGdx(); } protected static void initGdx() { // Initialize libgdx headless for use static vars (e.g. Gdx.input.setInputProcessor) final HeadlessApplicationConfiguration config = new HeadlessApplicationConfiguration(); config.renderInterval = 1f / 60; // Likely want 1f/60 for 60 fps new HeadlessApplication(mock(Core.class), config); <=== ERROR LINE } @BeforeMethod(alwaysRun = true) public void initMethod() throws Exception { // Initialize mocks MockitoAnnotations.initMocks(this); } }

错误:

推荐答案

我已解决此问题.我只是将initGdx();移至重载的beforePowerMockTestMethod()或beforePowerMockTestClass()并删除了Mockito注释初始化，因为它在父类中执行.

I'm fixed this. Im just move initGdx(); to overloaded beforePowerMockTestMethod() or beforePowerMockTestClass() and delete mockito annotations initialization because it execute in the parent class.

固定的AbsTest类:

fixed AbsTest class:

abstract public class AbsTest extends PowerMockTestCase { protected static void initGdx() { // Initialize libgdx headless for use static vars (e.g. Gdx.input.setInputProcessor) final HeadlessApplicationConfiguration config = new HeadlessApplicationConfiguration(); config.renderInterval = 1f / 60; // Likely want 1f/60 for 60 fps new HeadlessApplication(mock(Core.class), config); } @BeforeMethod @Override protected void beforePowerMockTestMethod() throws Exception { initGdx(); super.beforePowerMockTestMethod(); } }

或带有重载beforePowerMockTestClass方法

abstract public class AbsTest extends PowerMockTestCase { protected static void initGdx() { // Initialize libgdx headless for use static vars (e.g. Gdx.input.setInputProcessor) final HeadlessApplicationConfiguration config = new HeadlessApplicationConfiguration(); config.renderInterval = 1f / 60; // Likely want 1f/60 for 60 fps new HeadlessApplication(mock(Core.class), config); } @BeforeClass @Override protected void beforePowerMockTestClass() throws Exception { super.beforePowerMockTestClass(); initGdx(); } }
