将带有换行符的文本与另一个字符串匹配

Question

我正在尝试从弹出消息中获取文本，然后将其与另一个字符串进行比较以检查两者是否相同。

弹出屏幕

测试代码

var text = element(by.css('.modal.fade.AppLockPopup.in'));
//expect(text.getText()).toEqual("Warning" + "\n" + " You haven't saved your changes.Are "+ "\n" +" you sure you want to discard your changes? "+ "\n" +" Yes No");
expect(text.getText()).toEqual("Warning You haven't saved your changes.Are you sure you want to discard your changes? Yes No");

电流输出（失败）

如何比较这些字符串？

Answer 1

由于您遇到空格和换行符问题，我建议使用正则表达式将所有空白序列标准化为单个常规空格，然后再使用测试框架比较两个值：

var text = element(by.css('.modal.fade.AppLockPopup.in')).getText().then(function (e) {
  return e.replace(/\s+/g, ' ')
})

expect(text).toEqual(
  "Warning You haven't saved your changes. Are you sure you want to discard your changes? Yes No"
)

Answer 2

规范行尾和修剪内容对我确实有用：

  const normalizeContent = (content: string) => content.replace(/\r\n/g, "\n").trim();

  expect(normalizeContent(fileContent)).toEqual(normalizeContent(expected));

一如既往，享受。
