我们正在针对生产网站运行量角器(用打字稿写成)。量角器测试失败时,有人知道如何输出一些日志消息吗?我现在所拥有的基本上只是一个是/否消息,就像这样:
10) Query page accuracy test. Comparison of page data to data extracted from excel. Test begins...
Message:
Expected false to be truthy.
Stack:
Error: Failed expectation
at C:\xampp\htdocs\kap\frontend\src\app\qa\qa.js:147:103
at step (C:\xampp\htdocs\kap\frontend\src\app\qa\qa.js:33:23)
at Object.next (C:\...
等 这是我们测试的行:
expect(htmlValue == excelValue || (htmlValue === "0" && excelValue == "NaN")).toBeTruthy();
如果测试失败,如何添加更具描述性的消息?谢谢任何人,我在量角器中非常陌生,但是我之前已经做过QA自动化测试。

您可以像这样在ToBeTruthy
中添加说明:
expect(htmlValue == excelValue || (htmlValue === "0" && excelValue == "NaN")).toBeTruthy("description why I checked this")
如果您愿意,可以显示以下失败的测试值:
expect(
htmlValue == excelValue || (htmlValue === '0' && excelValue == 'NaN'),
).toBeTruthy(
`HTML differ form Excel. HTML: ${htmlValue}; Excel: ${excelValue}`,
);
几乎所有的茉莉花Matchers
都接受expectationFailOuput
参数:
toBe(expected: any, expectationFailOutput?: any): Promise<void>;
toEqual(expected: any, expectationFailOutput?: any): Promise<void>;
toMatch(expected: string | RegExp | Promise<string | RegExp>, expectationFailOutput?: any): Promise<void>;
toBeDefined(expectationFailOutput?: any): Promise<void>;
toBeUndefined(expectationFailOutput?: any): Promise<void>;
toBeNull(expectationFailOutput?: any): Promise<void>;
toBeTruthy(expectationFailOutput?: any): Promise<void>;
toBeFalsy(expectationFailOutput?: any): Promise<void>;
toContain(expected: any, expectationFailOutput?: any): Promise<void>;
toBeLessThan(expected: number | Promise<number>, expectationFailOutput?: any): Promise<void>;
toBeLessThanOrEqual(expected: number | Promise<number>, expectationFailOutput?: any): Promise<void>;
toBeGreaterThan(expected: number | Promise<number>, expectationFailOutput?: any): Promise<void>;
toBeGreaterThanOrEqual(expected: number | Promise<number>, expectationFailOutput?: any): Promise<void>;
toBeCloseTo(expected: number | Promise<number>, precision?: any, expectationFailOutput?: any): Promise<void>;
中找到Matchers定义。

您几乎可以在所有茉莉花匹配器中添加自定义消息,例如
expect(true).toBe(true, "This will be shown if the expectation will fail")
expect(htmlValue == excelValue || (htmlValue === "0" && excelValue == "NaN")).toBeTruthy(`Expected ${excelValue}` but got ${htmlValue });

虽然提出的解决方案可能有效,但使用它们并不是一个好习惯,仅仅是因为它需要更多的键入内容和不可读的代码
默认框架正式支持的两个选项是Jasmine:
对于Protractor 6+,您可以使用内置方法.withContext()
不幸的是,Jasmine团队没有提供太多文档。但是一般语法是expect(true).withContext("your description").toBe(false);
,并且可以用于任何Jasmine断言,而不仅是.toBeTruthy()
对于版本号<6的量角器,当每个断言带有两个参数时-一个未记录的功能-第一个是期望值,第二个-失败消息。例如
expect("first value").toBe("second value", "verification of some values")
失败并显示以下消息
- Expected 'first value' to be 'second value', 'verification of some values'.
