Compiles but doesn't run any tests

[amilbeck]

I'm having some trouble getting my tests to run. They compile fine but no tests are running. In fact, chrome isn't even launching which I find strange because it was launching fine and then failing when I had some compiler errors.

I've just joined a new project and the task I'm working on is migrating all the current unit and e2e tests to Jasmine. Previously the project was using mocha, sinon, chai, and mocha-webpack to run them. I've removed all of those dependencies and added the usual suspects as far as jasmine and karma-typescript are concerned. I setup my karma config based on the angular 2 example you have.

Here is a snippet of the logs from before I fixed the compiler error:

You can see that the launcher was working. However, now that I've fixed the compiler error all I'm getting is the project compiles and then karma exits.

Here is the logs from after the error was fixed:

START:
31 05 2018 15:57:54.525:INFO [compiler.karma-typescript]: Compiling project using Typescript 2.2.2

That's all I get. Have you ever seen this before? Know what the problem might be?

Here is my config for reference:

module.exports = function(config) {
    config.set({
        singleRun: true,
        frameworks: ["jasmine", "karma-typescript"],
        files: [
            { pattern: "src/**/*.+(ts|html)" }
        ],
        preprocessors: {
            "**/*.ts": ["karma-typescript"]
        },
        reporters: ["mocha", "karma-typescript"],
        browsers: ["Chrome"],
        karmaTypescriptConfig: {
            bundlerOptions: {
                entrypoints: /\.spec\.ts$/,
                transforms: [
                    require("karma-typescript-es6-transform")
                ]
            },
            compilerOptions: {
                target: "es5",
                module: "commonjs",
                moduleResolution: "node",
                sourceMap: true,
                emitDecoratorMetadata: true,
                experimentalDecorators: true,
                lib: ["es2015", "dom"],
                types: ["jasmine"],
                noImplicitAny: true,
                suppressImplicitAnyIndexErrors: true
              },
            exclude: [
                "node_modules",
                "e2e"
            ]
        }
    });
};

I'm really stumped. I don't understand why it at least attempted to run when there was an error but not at all once it was fixed. Any ideas would be greatly appreciated.

Ok, to add to my confusion, I added basePath: './src' and now it is launching the browser but still not running any of my tests. In fact, it doesn't look like any of my source files are even being loaded.

The karma-typescript-bundle.js file is completely empty for some reason

I ended up going a different route. Not sure what I was doing wrong here but I just couldn't get it to load any files no matter what I tried.
