答案:

错误代码是由于线路覆盖率低于我定义的值 (90%).它已经告诉我行覆盖率 86.8% 低于用户定义的 90% 值，所以我认为纱线不太可能重复报告"该错误.

the error code was due to line coverage being below the value that I defined (90%). It already told me line coverage 86.8% is below user defined value of 90% so I thought it unlikely that yarn would "double report" that error.
