在 grails 2.3.5 中使用 javascript 对页面进行 Geb 测试答案

【问题标题】：Geb Tests for pages with javascript in grails 2.3.5在 grails 2.3.5 中使用 javascript 对页面进行 Geb 测试
【发布时间】：2014-01-29 20:23:45
【问题描述】：

我正在从 grails 2.2.4 升级到 grails 2.3.5，我遇到的最后一个问题是 geb 功能测试。我已将geb 升级到0.9.2。

第一个问题是它似乎首先尝试将 geb 测试作为 spock 测试运行，即使没有任何 geb spock 测试，然后作为常规 geb 测试运行。

第二个问题是在这两种情况下启用 javascript 时，即在 GebConfig.groovy 中

driver = {
   def driver = new HtmlUnitDriver()
   driver.javascriptEnabled = true
    return driver

}

我得到以下异常：

当 javascript 未启用时，没有 javascript 的页面的测试通过，但有 javascript 的页面的测试得到以下结果：

对于如何处理这些问题有什么建议吗？这些测试在使用 grails 2.2.3 和 geb 0.9.0-RC-1 时通过

【问题讨论】：

也许您有一个以前被忽略/允许的 javascript 语法问题。如果您使用普通的浏览器驱动程序（例如 FirefoxDriver）运行它，它仍然会失败吗？您是否查看了 0.9.1 和 0.9.2 重大更改的列表？ Spock 运行测试是怎么回事？
@Gabriel 感谢您的回复。我确实检查了重大更改列表，但没有一个与我遇到的错误相匹配。我尝试设置 FirefoxDriver 和 ChromeDriver 失败。我不认为这是一个语法问题，因为它与我们编写的 JavaScript 文件以及一些来自 jQuery 的文件有关。但问题出在资源插件上。在 Config.groovy 的测试环境中设置 grails.resources.mappers.hashandcache.excludes = ['*/'] 修复了异常的问题。在 geb 0.9.1 和 0.9.2 中，测试运行两次：作为 spock 测试和作为功能测试，但在 0.9.0-RC-1 中只运行一次。
听起来你解决了你的主要问题。您可能只想回答自己的问题并接受它，这样人们就知道您想通了。至于作为 spock 测试运行，也许有一个类似的问题，您已将 Spock 配置为查找文件名的一些正则表达式，或者您 / 没有 / 已配置它并更改了默认值？（我不使用 Spock，所以这是我的猜测。）
Spock 现在默认带有 grails。我没有做任何 spock 配置。我不知道它为什么要运行两次测试，一次是 spock，一次是功能性的。

标签： javascript grails geb

【解决方案1】：

语法错误显然是由于资源插件和设置对javascript文件的哈希处理

grails.resources.mappers.hashandcache.excludes = ['*/']

在测试环境中的 Config.groovy 修复了异常的问题。

使用 geb 0.9.0-RC1 修复了测试运行两次的问题。很遗憾，我们无法升级到 0.9.2 的 geb。
