JUNIT Initialization Error
提问by Aleksandra Bienioszek
this is my code of file AllTests:
这是我的文件 AllTests 代码：
import org.junit.runner.RunWith;
import org.junit.runners.Suite;
@RunWith(Suite.class)
@Suite.SuiteClasses({
ElementTests.class
})
public class AllTest {}
ElementTests.java
元素测试.java
import org.junit.Test;
import pl.polsl.lab1.Model.*;
import static org.junit.Assert.*;
import org.junit.Test;
public class ElementTests {
@Test
public void properSymbolPlayerTest()
{
//given
ElementOfBoard element = new ElementOfBoard();
ElementOfBoard element2 = new ElementOfBoard();
//when
element.setSymbol(1);
element.setSymbol(2);
//then
assertEquals('O', element);
assertEquals('X', element2);
}
}

- Right click your project in Package Explorer > click Properties go to Java Build Path > Libraries tab click on 'Add Library' button select JUnit click Next.
- 在 Package Explorer 中右键单击您的项目 > 单击 Properties 转到 Java Build Path > Libraries 选项卡单击“Add Library”按钮选择 JUnit 单击 Next。
That should solve this problem.
那应该可以解决这个问题。
回答by Vaishnavi R
In my case the issue was I had accidentally commented out @Testbefore the method I was trying to test. So it was throwing the initialization error and method not available.
就我而言，问题是我在尝试测试的方法之前不小心注释掉了@Test。所以它抛出了初始化错误和方法不可用。
This can also happen if we have @Ignore on the class level.
如果我们在类级别有 @Ignore，也会发生这种情况。

Please check @Test annotaionis added and imported from the right import path import org.junit.Test;
请检查@Test annotaion是否从正确的导入路径添加和导入import org.junit.Test;
