如何创建扩展,它只对整个大 class 内部有许多嵌套的 classes 运行一次 beforeAll
How to create Extension which runs beforeAll only once for whole big class with many nested classes inside
鉴于我测试的 class 内部有许多嵌套的 classes:
class TestWithManyNested {
@RegisterExtension
static MyExtension extension = new MyExtension();
@Nested
class Nested1 {
@Test
void nested1() {
}
}
@Nested
class Nested2 {
@Test
void nested2() {
}
}
}
这是我的简单扩展:
static class MyExtension implements BeforeAllCallback, AfterAllCallback, BeforeEachCallback, AfterEachCallback {
@Override
public void beforeAll(ExtensionContext extensionContext) throws Exception {
System.out.println("beforeAll");
}
@Override
public void afterAll(ExtensionContext extensionContext) throws Exception {
System.out.println("afterAll");
}
}
我如何 运行 我的 TestWithManyNested
和 MyExtension
整个测试 运行 beforeAll
只有一次
如果你只想对最外层class执行class级回调,你可以重写你的扩展如下(检查最外层没有"enclosing class" class).
static class MyExtension implements BeforeAllCallback, AfterAllCallback {
@Override
public void beforeAll(ExtensionContext extensionContext) throws Exception {
Class<?> testClass = extensionContext.getRequiredTestClass();
if (testClass.getEnclosingClass() == null) {
System.err.println("beforeAll: " + testClass.getName());
}
}
@Override
public void afterAll(ExtensionContext extensionContext) throws Exception {
Class<?> testClass = extensionContext.getRequiredTestClass();
if (testClass.getEnclosingClass() == null) {
System.err.println("afterAll: " + testClass.getName());
}
}
}
