挑选待运行测试用例
<p>[TOC]</p>
<h1>1、静态挑选待运行测试用例</h1>
<p>是指给测试用例添加关键字如：.only()、.skip()、或者指定 runFlag 且在运行时指定 runFlag 的值</p>
<h1>2、动态挑选待运行测试用例</h1>
<pre><code>推荐使用插件2，插件1作为参照对比</code></pre>
<h4>什么是动态挑选待运行测试用例</h4>
<p>指给测试用例添加一个或多个相应描述关键字，在运行时，指定相应的关键字，运行或排斥测试用例</p>
<h2>A、插件1 （cypress-select-tests）</h2>
<h4>如何动态挑选待运行测试用例</h4>
<p>使用 cypress-select-tests 插件
官方：<a href="https://github.com/bahmutov/cypress-select-tests">https://github.com/bahmutov/cypress-select-tests</a></p>
<h4>安装插件</h4>
<p>注意：目前最高仅支持到<code>cypress@7.4.0</code></p>
<pre><code>npm install --save-dev cypress-select-tests</code></pre>
<h4>设置插件</h4>
<pre><code>const selectTestsWithGrep = require('cypress-select-tests/grep')
module.exports = (on, config) => {
on('file:preprocessor', selectTestsWithGrep(config))
}</code></pre>
<h4>指定测试用例运行的栗子</h4>
<pre><code>context('指定测试用例运行的栗子', function () {
it('[smoke] 登录用例1', function () {
cy.log('登录成功')
});
it('[e2e,smoke] 登录用例1', function () {
cy.log('登录成功')
});
})</code></pre>
<h4>执行以下命令</h4>
<pre><code>npx cypress open --env grep=e2e</code></pre>
<ul>
<li>打开 Cypress 运行器，运行测试用例文件</li>
<li>--env grep=e2e 的作用：指定包含 e2e 标签的测试用例运行
<h5>使用该插件的重点</h5>
<p>其实就是【写标签，通过各种方式传递环境变量】，以下是通过 CLI 方式传递环境变量的几种写法和对应的作用</p>
<pre><code>\# 仅运行带有 works 标签的测试用例
yarn cypress open --env grep = works
\# 仅运行文件名中带有 foo 的文件
yarn cypress open --env fgrep = foo
\# 仅运行文件名中带有 foo 的文件，且仅运行文件中带有 works 标签的测试用例
yarn cypress open --env fgrep = foo，grep = works
\# 仅运行带有 '功能A' 标签的测试用例
yarn cypress open --env grep ='功能A'
#仅运行文件名中不带有 foo 的文件
yarn cypress open --env fgrep = foo，invert = true
#仅运行不带有 works 标签的测试用例
yarn cypress open --env grep = works，invert = true</code></pre>
<h2>B、插件2 （cypress-grep）</h2>
<p>使用用例的name和tags挑选用例</p>
<h4>安装插件</h4>
<pre><code>npm install --save-dev cypress-grep</code></pre>
<h4>引入</h4>
<p>cypress/support/index.js</p>
<pre><code>const registerCypressGrep = require('cypress-grep')
registerCypressGrep()</code></pre>
<p>cypress/plugins/index.js</p>
<pre><code>module.exports = (on, config) => {
require('cypress-grep/src/plugin')(config)
return config
}</code></pre>
<h4>使用</h4>
<pre><code># run only the tests with "auth user" in the title
$ npx cypress run --env grep="auth user"
# run tests with "hello" or "auth user" in their titles
# by separating them with ";" character
$ npx cypress run --env grep="hello; auth user"
# run tests tagged @fast
$ npx cypress run --env grepTags=@fast
# run only the tests tagged "smoke"
# that have "login" in their titles
$ npx cypress run --env grep=login,grepTags=smoke
# only run the specs that have any tests with "user" in their titles
$ npx cypress run --env grep=user,grepFilterSpecs=true
# only run the specs that have any tests tagged "@smoke"
$ npx cypress run --env grepTags=@smoke,grepFilterSpecs=true
# run only tests that do not have any tags
# and are not inside suites that have any tags
$ npx cypress run --env grepUntagged=true</code></pre>
<h4>推荐使用方式</h4>
<p>将<code>grepFilterSpecs</code>和<code>grepOmitFiltered</code>两个参数设置再环境变量中，参数含义见<a href="https://github.com/cypress-io/cypress-grep" title="参考">官方文档</a></p>
<pre><code> "env": {
"grepFilterSpecs": true,
"grepOmitFiltered": true
}</code></pre>
<p>用例中加tag的方式</p>
<pre><code> it('删除已经存的statefulset资源',{ tags: ['smoke', 'some-other-tag'] }, () => {
cy.loadPage('statefulset', orgId, projectId, envId, env, clusterId, cluster, appName, appId);
statefulsetListPage.checkIfResourceExist(appName);
})</code></pre>
