期望在Pagesource-Protractor中不存在文本

Question

我需要获取Pagesource＆amp;然后检查pagesource中是否不存在" Hello World"。

我正在尝试下面的方法。

var page_source=browser.getPageSource().then(function (text){
    expect(text).not.toContain("hello world");
});

任何建议??

Answer 1

尝试此正则表达方式以符合您的要求。

示例：

 it("The 'toMatch' matcher is for regular expressions", function() {
     var message = "foo bar baz";
     expect(message).toMatch(/bar/);
     expect(message).toMatch("bar");
     expect(message).not.toMatch(/quux/);
  });

fyi - tocontain（） - 用于在数组中查找项目。

示例：

 it("works for finding an item in an Array", function() {
     var a = ["foo", "bar", "baz"];
     expect(a).toContain("bar");
     expect(a).not.toContain("quux");
  });

几个建议。

1. 您无需解决承诺。茉莉花期望为您

expect(browser.getPageSource()).not.toContain("hello world")

是的，您正在做的是正确的 - 其余的 - 我的意思是茉莉花主张和使用not是正确的，它应该按预期工作

如果您基于 Angular 使用应用程序，请执行某件事

由于https://github.com/angular/protractor/blob/master/master/docs/timeouts.md#how-to-dis-disable-waiting-for-angular，您应该 disable等待等待角度本身。

示例：

describe('Google Site Verification', () => {
    beforeEach(() => {
        browser.waitForAngularEnabled(false);
        browser.get(browser.baseUrl);
    });
    afterEach(() => {
        browser.waitForAngularEnabled(true);
    });
    it('should be injected', () => {
        const source = browser.getPageSource();
        expect(source).toMatch(/google-site-verification/i);
    });
});
