Running tns test android does not detect tests and is stuck in `test: loading; `

Environment

• CLI: 8.1.4
• karma: 6.3.7
• karma-jasmine: 4.0.1
• karma-webpack: 5.0.0
• karma-nativescript-launcher: ~2.9.0

Describe the bug

I initalized tests using tns test init using jasmine. After running tns test android, in the browser the header shows test: loading and it doesn't appear to load any test files in the network tab. The mobile app that's launched on my emulator shows no tests. I did not make any modifications to the version of the dependencies or to the generated karma.conf.js. There were no errors in the logs.

To Reproduce

Run tns test init and select jasmine
Run tns test android, it launches the app with no tests displayed. In the browser, it displays test:loading

Expected behavior
My unit tests to be displayed and their status.

首先使用 tns test init 重现该问题，选择 Jasmine，然后运行 tns test android；在模拟器启动时检查生成的 karma.conf.js 和浏览器网络活动。将预期的测试加载流程与观察到的 test: loading 状态进行比较，当初始化的单元测试及其状态出现在浏览器和模拟器中时，即可认为问题已完成。
