问题描述

我有一个量角器设置通过 multiCapabilities 配置多个浏览器,在browserstack运行测试。

I have a protractor setup with multiple browsers configured through multiCapabilities, running tests on browserstack.

我的一个关键量角器规格的/测试包含以下 afterEach()块:

One of my key protractor specs/tests contain the following afterEach() block:

afterEach(function() {
    browser.manage().logs().get("browser").then(function (browserLog) {
        expect(browserLog.length).toEqual(0);
    });
});

这将检查浏览器控制台为空(在控制台上没有错误)。

that checks that the browser console is empty (no errors on the console).

的问题是:当我运行针对Internet Explorer的这个天赋,我发现了一个不明错误

The problem is: when I run this spec against Internet Explorer, I'm getting an UnknownError:

不明错误:找不到命令:P​​OST /会话/ 6b838fe8-f4a6-4b31-B245-f4bf8f37537c /日志

UnknownError: Command not found: POST /session/6b838fe8-f4a6-4b31-b245-f4bf8f37537c/log

一个快速研究后,我发现, IE硒的webdriver 尚不支持会话日志:

After a quick research, I've found out that IE selenium webdriver does not yet support session logs:

  • [IE] Add support for fetching logs using the webdriver.manage().logs() mechanism

现在的问题是:我怎么能抓住这个不明错误,让规范通在此特定错误的情况下

The question is: how can I catch this UnknownError and let the spec pass in case of this specific error?

或者,围着它转,是有可能有一个 afterEach()块能力/浏览器特定的,或者知道当前运行的能力是什么呢?

Or, to turn it around, is it possible to have an afterEach() block capability/browser-specific, or know which currently running capability is it?

我试图用的try / catch 并试图依靠例外发件人,但的console.log()不执行:

I've tried to use try/catch and try relying on exception sender, but console.log() is not executed:

afterEach(function() {
    try {
        browser.manage().logs().get("browser").then(function (browserLog) {
            expect(browserLog.length).toEqual(0);
        });
    }
    catch (e) {
        console.log(e.sender);
    }
});

作为一种解决办法,我重复相同的规范,但没有不及格的 afterEach()块,专门针对IE浏览器。

As a workaround, I'm duplicating the same spec but without that failing afterEach() block, specifically for Internet Explorer.

推荐答案

找到一个选择 - 使用的 的getCapabilities() 检索当前浏览器的名称:

Found one option - using getCapabilities() to retrieve the current browser name:

afterEach(function() {
    browser.driver.getCapabilities().then(function(caps) {
        var browserName = caps.caps_.browserName;

        if (browserName !== "internet explorer") {
            browser.manage().logs().get("browser").then(function (browserLog) {
                expect(browserLog.length).toEqual(0);
            });
        }
    });
});

在这种情况下,浏览器日志将不会对是否Internet Explorer中运行检查。

In this case browser logs would not be checked if running against Internet Explorer.
