处理量角器中的未知错误 [英] Handling Unknown Errors in protractor
问题描述
我有一个量角器
设置,多个浏览器通过 multiCapabilities
配置,在browserstack上运行测试。
我的一个关键的量角器规格/测试包含以下 afterEach()
块:
afterEach(function(){
browser.manage()。logs()。get(browser)。then(function(browserLog){
expect(browserLog.length).toEqual(0);
});
});
检查浏览器控制台是否为空(控制台上没有错误)。
问题是:当我针对Internet Explorer运行这个规范时,我得到一个 UnknownError
:
UnknownError:找不到命令:POST / session / 6b838fe8-f4a6-4b31-b245-f4bf8f37537c / log
经过快速研究,我发现 IE selenium webdriver
尚不支持会话日志:
问题是:如何捕获这个 UnknownError
,并在特定错误的情况下通过spec?
或者,要解决它,可能有一个 afterEach()
块功能y /浏览器特定的,或者知道当前运行的功能是什么?
我试图使用 try / catch
并尝试依赖例外发件人
,但 console.log()
不执行:
afterEach(function(){
try {
browser.manage ).logs()。get(browser)。then(function(browserLog){
expect(browserLog.length).toEqual(0);
});
}
catch(e){
console.log(e.sender);
}
});
作为解决方法,我重复相同的规范,但没有失败的 afterEach()
阻止,专门用于Internet Explorer。
找到一个选项 - 使用 getCapabilities()
来检索当前的浏览器名称:
$ pre>
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,如果针对Internet Explorer运行,浏览器日志将不会被检查。
I have a protractor
setup with multiple browsers configured through multiCapabilities
, running tests on browserstack.
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);
});
});
that checks that the browser console is empty (no errors on the console).
The problem is: when I run this spec against Internet Explorer, I'm getting an UnknownError
:
UnknownError: Command not found: POST /session/6b838fe8-f4a6-4b31-b245-f4bf8f37537c/log
After a quick research, I've found out that IE selenium webdriver
does not yet support session logs:
The question is: how can I catch this UnknownError
and let the spec pass in case of this specific error?
Or, to turn it around, is it possible to have an afterEach()
block capability/browser-specific, or know which currently running capability is it?
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);
}
});
As a workaround, I'm duplicating the same spec but without that failing afterEach()
block, specifically for Internet Explorer.
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);
});
}
});
});
In this case browser logs would not be checked if running against Internet Explorer.
