Ionic Jasmine：env.stopOnSpecFailure在编译成功后不是函数 [英] Ionic Jasmine : env.stopOnSpecFailure is not a function after compiled successfully

问题描述

使用Ionic与jasmine-karma，在运行测试时，获得成功编译，但在jasmine仪表板中，在控制台中出现空白屏幕错误。

Using Ionic with jasmine-karma, while run test, getting success compile but in jasmine dashboard getting empty screen with error in console.

以下教程： https://leifwells.github.io / 2017/08/27 / testing-in-ionic-configure-existing-projects-for-testing /

"ts-loader": "^4.1.0",
"jasmine-core": "^2.99.1"

错误消息：

TypeError: env.stopOnSpecFailure is not a function at adapter.js:26

Error: Module build failed: TypeError: Cannot read property 'afterCompile' of undefined

推荐答案

尝试使用stopOnSpecFailure函数的karma-jasmine版本发生故障。您的jasmine-core版本中不存在该功能，您需要版本3或更高版本。版本3.1.0现在是最新的，并且运行良好。另请注意，如果您使用的是Webpack 3，还应降级ts-loader到3.5.0 。

The failure occurs in your version of karma-jasmine which tries to use the stopOnSpecFailure function. That function is not present in your version of jasmine-core, you'll need version 3 or greater. Version 3.1.0 is the newest right now and works good. Also note that if you're using Webpack 3 you should also downgrade ts-loader to 3.5.0.

更新：

我注意到有很多人建议将茉莉核心降级为2.99.1。显然人们在使用jasmine-core 3时遇到了问题。如果是这种情况，那么你可以使用 karma-jasmine-html-reporter 0.2.2版和jasmine-core 2.99.1。

I noticed that many people suggests downgrading jasmine-core to 2.99.1. Apparently people have problems using jasmine-core 3. If that's the case for you, then you can use karma-jasmine-html-reporter version 0.2.2 together with jasmine-core 2.99.1.
