如何在单元测试中覆盖分支

Question

I have this function which needs to be unit tested,

I've wrote few specs which is working fine. But in the code-coverage it says Else path not taken for this line if (text !== '') {} .

I'm not sure how to test variable inside the function.

Below are few specs which I wrote.

  it('should split the content correctly', inject([GenerateInlineTagsService], (service: GenerateInlineTagsService) => {
    const obj = service.getView(RANGES);
    expect(JSON.stringify(obj)).toEqual(JSON.stringify(inlineSplitContent));
  }));

Answer 1

Create a new test case and pass below value to your function while testing so that else branch would be taken:

const content = { inlineEntityRanges: [], text: '' }

Also, if possible write else block of each if block as while measuring branch coverage these things are required.
