Java Junit testing problem
提问by user238384
I am using Junit 4. My whole program is working fine. I am trying to write a test case. But there is one error...
我正在使用 Junit 4。我的整个程序运行良好。我正在尝试编写一个测试用例。但是有一个错误...
here is very basic sample test
这是非常基本的样本测试
public class di extends TestCase{
private static Records testRec;
public void testAbc() {
Assert.assertTrue(
"There should be some thing.",
di.testRec.getEmployee() > 0);
}
}
and when i run this it give me error that
当我运行它时，它给了我错误
fName can not be null
if i use super and do like this
如果我使用 super 并且这样做
public TestA() {
super("testAbc");
}
it work all fine. It wasn't this before with JUnit 3.X am I doing wrong or they changed it :( Sorry if I am not clear
一切正常。JUnit 3.X 之前不是这样的，是我做错了还是他们改变了它:( 对不起，如果我不清楚
Is there any way to executre test without super? or calling functions etc. ?
有没有办法在没有超级的情况下执行测试？或调用函数等？

In JUnit 4 you need not extend TestCase, instead use the @Testannotation to mark your test methods:
在 JUnit 4 中，您不需要扩展TestCase，而是使用@Test注释来标记您的测试方法：
public class MyTest {
private static Records testRec;
@Test
public void testAbc() {
Assert.assertTrue(
"There should be some thing.",
MyTest.testRec.getEmployee() > 0);
}
}
As a side note, testing a staticmember in your class may make your unit tests dependent on each other, which is not a good thing. Unless you have a very good reason for this, I would recommend removing the staticqualifier.
作为旁注，测试static类中的成员可能会使您的单元测试相互依赖，这不是一件好事。除非您有充分的理由，否则我建议删除static限定符。

This is not your case but this error may also mean that you have a file named Test.javain your project. Renaming it will fix the error but after refactoring @Testwill be changed to @NewName(at least in Eclipse) so remember to manually change it back to @Test.
这不是您的情况，但此错误也可能意味着Test.java您的项目中有一个文件名。重命名将修复错误，但重构@Test后将更改为@NewName（至少在 Eclipse 中），因此请记住手动将其更改回@Test.
