浏览器启动前的 Codeception 验收测试 运行

Question

当我 运行 Codeception 测试时，有时在验收测试中浏览器启动太晚，测试不会等待它启动，并且在浏览器启动之前通过的测试会出现错误：

[ConnectionException] Can't connect to Webdriver at http://127.0.0.1:4444/wd/hub. Please make sure that Selenium Server or PhantomJS is running.

#1 Codeception\Subscriber\Module->before

#2 D:\path\Yii\basic\vendor\symfony\event-dispatcher\EventDispatcher.php:212

#3 D:\path\Yii\basic\vendor\symfony\event-dispatcher\EventDispatcher.php:44

有一次浏览器根本没有启动。

我的命令：

C:\Windows\System32\cmd.exe /K "cd /D D:\path\Yii\basic && vendor\bin\codecept run"

acceptance.suite.yml:

class_name: AcceptanceTester

    enabled:

            - java -jar -Dwebdriver.chrome.driver="D:/Selenium/chromedriver.exe" -Dwebdriver.gecko.driver="D:/Selenium/geckodriver.exe" "D:/Selenium/selenium-server-standalone-3.6.0.jar"

            part: orm
            entryScript: index-test.php
            cleanup: false

            cleanup: false

coverage:
    enabled: true
    whitelist:
        include:
            - models/*
            - controllers/*

向 RunProcess 配置添加一些睡眠

To wait for the process to be launched use sleep option. In this case you need configuration to be specified as object:

extensions:
    enabled:
        - Codeception\Extension\RunProcess:
            0: java -jar ~/selenium-server.jar
            1: mailcatcher
            sleep: 5 # wait 5 seconds for processes to boot
