Automation expect就是抛出一个“expect”；AssertionError:预期{Object（browser），then，…}等于true"；

我的测试中的expect有一个错误

我犯了这个错误

我试图做的是验证一个元素是否被选中，因此阅读我看到的另一个建议，

.isSelected（）

是最好的选择，但我不确定为什么抛出这个错误

希望你能帮助我

看起来您正在尝试将对象与布尔值进行比较。 如果您使用“chai”作为断言库，则必须解决这样做的承诺，否则使用“finally”。样本如下：

expect(element(".//div[@class='md-whiteframe-1dp outset inset']/md-checkbox").isSelected()).to.eventually.equal(true);

或

要找出使用expect with Promissions的正确方法需要一些时间。

我建议查看异步/等待语法。您还可以尝试在此处使用

browser.wait（ExpectedConditions.elementToBeSelected）

Then('Validate role {editrole} is selected', { timeout:30 * 1000 }, async (editrole) => {
    const agentRoles = element.all(by.repeater('ctrl.roles'))
    expect(await agentRoles.count()).not.to.be(0)
    await browser.wait(ExpectedConditions.elementToBeSelected(
        element(by.cssContainingText('div.md-whiteframe-1dp.outset.inset md-checkbox', editrole))
    ), 10000, `Expected ${editrole} to be selected`);
});

element(".//div[@class='md-whiteframe-1dp outset inset']/md-checkbox").isSelected().then(function (select) {
    expect(select).to.be.true;
});

Then('Validate role {editrole} is selected', { timeout:30 * 1000 }, async (editrole) => {
    const agentRoles = element.all(by.repeater('ctrl.roles'))
    expect(await agentRoles.count()).not.to.be(0)
    await browser.wait(ExpectedConditions.elementToBeSelected(
        element(by.cssContainingText('div.md-whiteframe-1dp.outset.inset md-checkbox', editrole))
    ), 10000, `Expected ${editrole} to be selected`);
});
