'Executed 0 of 0 ' : No tests detected with Typescript, Jasmine, Enzyme, Karma #480

Open cefn opened 3 years ago

cefn commented 3 years ago

In https://github.com/monounity/karma-typescript/issues/341 many reporters shared an issue they encountered.

After an apparent fix to suppress issues when calculating coverage, we have the remaining situation where karma-typescript runs, but detects 0 tests.

For many it was a dead end meaning they couldn't get karma-typescript to work at all, and could have been that way for 2 years. It's probably just a common misconfiguration but knowing the workaround, or maybe improving error messages could be key to people not getting totally stuck.

REPRODUCING

Since #341 might have quite a few different issues going on for the different posters, I have put together a minimal repro of the configuration which led me to encounter the narrow issue of Executed 0 of 0 at https://github.com/cefn/karma-typescript-failure and I am reporting it as a new issue.

It can be reproduced by running...

npm install
npm run test

The run fails presumably because it has detected 0 tests but I don't know why it doesn't detect the App.test.tsx, although it seems to load the corresponding file.

I don't know if istanbul is connected to the no-detected-tests error, but note, the option coverageOptions: { instrumentation: false }, was added to karmaTypescriptConfig to avoid the fatal error 03 07 2021 17:01:22.970:ERROR [karma-server]: UncaughtException: TypeError: Cannot read property 'startsWith' of undefined at Coverage.hasNoOutput (/home/cefn/Desktop/karma-typescript-failure/node_modules/karma-typescript/dist/istanbul/coverage.js:56:38)

THEORY

Theory so far is that some kind of js file output is expected but none actually takes place, meaning App.test.js doesn't exist. However, I don't know what the correct mechanism is meant to be for karma-typescript to hand over the transpiled files, and it claims to 'serve cached'.

I cloned your example and set a breakpoint with at node_modules\karma-typescript\dist\istanbul\coverage.js:35 with conditional emitOutput.outputText == undefined and it was hit with App.test.tsx. When inspecting this.config.coverageOptions.exclude I saw that this was set to /\\.(d|spec|test)\\.ts$/i. Looks like karma-typescript does not exclude *.test.tsx files from coverage instrumentation by default. But this also raises the question, why there is no output for App.test.tsx. I didn't have more time to investigate further, but hope this helped you a little already.

I don't think this needs a seperate issue, as this seems to be configuration error in the project. Nevertheless I agree that this might probably need some better handling or a more understandable message, but I would propose to leave that discussion in #341.

cefn commented 3 years ago

Just to clarify, Tim. I am not particularly concerned regarding coverage, and would accept any configuration which actually makes tests run. Crucially I currently get this output...

Chrome 91.0.4472.114 (Linux x86_64): Executed 0 of 0 SUCCESS (0 secs / 0 secs)
Chrome 91.0.4472.114 (Linux x86_64): Executed 0 of 0 SUCCESS (0.001 secs / 0 secs)

That's one reason for separating out this issue from the many configurations, errors discussed in #341 (depending on what particular workaround for the startsWith error is attempted).

Additionally having 0 tests detected is an error with a complete repro where this detail is absent in #341 making it well-scoped.

So to refocus this issue explicitly away from property 'startsWith', what variation do I have to make for Karma to see any of my tests and run them in any form, regardless of coverage?

I can close if you instruct me to, and if you feel the scope of this error really is the same as the 'startsWith' issue, but I don't think I've understood how the startsWith error and the 0 of 0 SUCCESS error are the same thing currently.

I'll change the title to reflect the intended scope.

timvahlbrock commented 3 years ago

With the modification of the title this seems to be scoped better. 👍

Wrapping the Typescript compilation process rather than going full webpack and full babel is my preference. Seems more elegant and don't have to dance through hoops for sourcemaps etc. I have a workaround for now following the babel route (with all the horrid extra packages, config). This means I can run Karma tests in my personal project so it's less urgent, I wanted to at least share a repro of a pretty minimal problem case config back to karma-typescript for it to be worked on. I'm puzzling what's different about how me (and others) have approached composing our project which triggers a bug, since presumably everyone else is using the utility perfectly well.

Thank you for opening this issue, I am facing a similar problem in my repo: https://github.com/status-im/js-waku/pull/230 with no test being executed Chrome 91.0.4472.114 (Linux x86_64): Executed 0 of 0 SUCCESS (0 secs / 0 secs)

@D4nte so I gather in your case from https://github.com/monounity/karma-typescript/issues/341#issuecomment-879531928 it was resolved by ensuring .js files are emitted.

I don't know why this doesn't work in my case. Although I have noEmit:false https://github.com/cefn/karma-typescript-failure/blob/master/tsconfig.json#L7 I still get 0 of 0 tests.

It was a shame but I ended up having to completely transform how I built my whole project to be able to use Karma - no longer relying directly on Typescript tooling and having to go via babel=>webpack route. I put together a reference repository with working tests but the different build system at https://github.com/cefn/typescript-karma-counter#readme

I would much rather use karma-typescript!

When inspecting this.config.coverageOptions.exclude I saw that this was set to /\.(d|spec|test)\.ts$/i. Looks like karma-typescript does not exclude *.test.tsx files from coverage instrumentation by default. But this also raises the question, why there is no output for App.test.tsx.

@cefn did you have a chance to take a further look into this? My experience with Karma is that sometimes build errors don't crash the run but cause trouble later in the browser. I could imagine that karma-typescript does not compile tsx files by default and the 0 of 0 in the browser is caused by the test-file failing to load the compilation result.

I did what I could to nudge karma-typescript into doing the right thing with...

https://github.com/cefn/karma-typescript-failure/blob/master/karma.conf.js#L8-L9

https://github.com/cefn/karma-typescript-failure/blob/master/karma.conf.js#L18

https://github.com/cefn/karma-typescript-failure/blob/master/tsconfig.json#L17

However, I think it might take a karma-typescript expert to know what directives it respects, and if there's another one it needs, since this is all 'declarative' so I can't even really step through the procedure to see where it goes wrong.

Yes but not only. Please check my PR https://github.com/status-im/js-waku/pull/230, it took me an afternoon to better understand karma and karma-typescript config options so I can fine tune to perfect. See below:

process.env.CHROME_BIN = require('puppeteer').executablePath(); // Puppeteer installs Chrome for in GitHub Action CI

module.exports = function (config) {
  config.set({
    frameworks: ['mocha', 'karma-typescript'], // Using mocha and karma-typescript
    files: [
      'src/lib/**/*.ts', // This contains my library files that can all be ran in the browser
      'src/proto/**/*.ts', // Note I have some NodeJS files to help with some test setup, they are NOT in these folders
    ],
    preprocessors: {
      '**/*.ts': ['karma-typescript'],
    },
    plugins: [
      require('karma-mocha'),
      require('karma-typescript'),
      require('karma-chrome-launcher'),
    ],
    reporters: ['progress', 'karma-typescript'],
    browsers: ['ChromeHeadless'],
    singleRun: true,
    karmaTypescriptConfig: {
      bundlerOptions: {
        entrypoints: /src\/tests\/browser\/.*\.spec\.ts$/, // This is maybe what is missing, I explicitly state what are the test files
      },
      tsconfig: './tsconfig.karma.json', // See below
      coverageOptions: {
        instrumentation: false,
      },
    },
  });
};

and tsconfig.karma.json

{
  "extends": "./tsconfig",
  "compilerOptions": {
    "noEmit": false // this should not be necessary but it ensures JS files are emitted
  },
  "include": [ // I override this value to ONLY include files that can run in the browser, excluding NodeJS test utils (that uses fs, etc)
    "src/lib/**/*.ts",
    "src/proto/**/*.ts",
    "src/tests/browser/**/*.ts"
  ],
  "exclude": ["node_modules/**"] // my `tsconfig.json` files excludes test files to ensure they are not include in the NPM package so I override it to allow the test files to be compiled and ran in the browser.
}

Here is an alternative to avoid the separate tsconfig file, note how I need to use mode: 'replace' to make it work: d12430e (#231)
