如何在IntelliJ IDEA中获取实际的代码覆盖率报告？

我有一个简单的类，叫做SomeClass：

public class SomeClass {

    public int value = 0;

    public void inc() {
        value++;
    }

    public void dec()
    {
        if (isBiggerThanFive()) value--;
        value--;
    }

    private boolean isBiggerThanFive() {
        return value > 5;
    }
}

还有一个测试类TheTest：

class TheTest {

    SomeClass t;

    @BeforeEach
    void setUp() {
        t = new SomeClass();
    }

    @Test
    public void whenNewTestIsCreated_ValueIsZero()
    {
        assertEquals(t.value, 0);
    }

    @Test
    public void whenIncIsCalledWithValueOfZero_ValueIsOne()
    {
        t.inc();
        assertEquals(t.value, 1);
    }

    @Test
    public void whenDecIsCalledWithValueOfZero_ValueIsNegativeOne()
    {
        t.dec();
        assertEquals(t.value, -1);
    }
}

注意函数dec的结构以及整个if条件和语句如何在同一行。在测试中，当值大于5时，这部分递减2而不进行测试。因此，我认为我应该在覆盖率报告中看到这一部分没有涉及。但这就是我得到的：

相反，当我让陈述独立存在时，我会得到正确的结果：

Even though the code is completely the same, I get different results based on just the structure of the code. How can I have an indication that a part of a line isn't covered when it's not acutally covered?
