Question

我正在尝试从Gradle启动Selenium以运行Protractor测试。

这是我的Gradle脚本：

//main task to run protractor tests
task uiTests << {
    println "Starting protractor tests"
}

//start Selenium server
task startSelenium << {
    println "Starting Selenium..."
    ant.exec(executable: '/bin/bash', spawn: true) {
        arg(value:'webdriver-manager')
        arg(value:'start')
    }
}

//run protractor
task runProtractor(type: Exec) {
    commandLine 'protractor', 'bignibou-client/protractor.conf.js'
}

//start selenium, then run protractor
uiTests.dependsOn([startSelenium, runProtractor])

但是，输出似乎表明Selenium进程尚未启动：

 :runProtractor

* What went wrong:
Execution failed for task ':runProtractor'.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

有人可以提供明智的提示和指导吗？

通过直接引用webdriver-manager脚本，如下所示排序问题：

//main task to run protractor tests
task uiTests << {
    println "Starting protractor tests"
}

//start Selenium server
task startSelenium << {
    println "Starting Selenium..."
    ant.exec(executable: 'webdriver-manager', spawn: true) {//CHANGED!!
        arg(value: 'start')
    }
}

//run protractor
task runProtractor(type: Exec) {
    commandLine 'protractor', 'bignibou-client/protractor.conf.js'
}

//start selenium, then run protractor
uiTests.dependsOn([startSelenium, runProtractor])

从Gradle运行Selenium webdriver-manager
