有没有办法通过IntelliJ IDEA中的方法查看所有路径？

Question

I'm writing unit tests for a Java method which contains nested if statements. I want to write a test for each path through the method. However, I'm finding it hard work to identify all the paths.

Here's an example method through which there are three paths:

public void myMethod(int i) {
    if (i % 2 == 0)
        System.out.println("foo");
    else {
        if (i % 3 == 0)
            System.out.println("bar");
        else
            System.out.println("baz");
    }
}

For this method, I'd want an output something like:

1. if (i % 2 == 0) -> System.out.println("foo");
2. if (i % 2 == 0) -> if (i % 3 == 0) -> System.out.println("bar");
3. if (i % 2 == 0) -> if (i % 3 == 0) -> System.out.println("baz");

Does a feature like this exist in IntelliJ IDEA? And if not, is there another tool that'll do the job?

运行覆盖测试（在调试图标旁边），然后您可以看到您已覆盖的内容。
