A Jasmine Console Reporter that remaps Typescript files. This will use source maps to remap the error stack file paths and line numbers to the source typescript files.

npm i --save-dev jasmine-ts-console-reporter

Just use --reporter=jasmine-ts-console-reporter argument when calling jasmine command line tool, for example, from your package.json file:

"scripts": {
	"test": "tsc ; jasmine --reporter=jasmine-ts-console-reporter"
},

IMPORTANT Don't forget to configure the TypeScript compiler to generate sourcemaps, for example adding "sourceMap": true in your tsconfig.json

Create a helper file for jasmine, eg specs/helpers.js

const TSConsoleReporter = require('jasmine-ts-console-reporter');

jasmine.getEnv().clearReporters(); // Clear default console reporter
jasmine.getEnv().addReporter(new TSConsoleReporter());

Load the helper file in Jasmine, eg on node jasmine.json:

{
	"helpers": [
		"specs/helpers.js",
	]
}

For more intricate usage scenarios, like using istanbul where the sourcemaps for instumented files are held in memory, you can locate the sourcemaps via a callback:

new TSConsoleReporter({
	sourceMapProvider: (fileName) => {
		const map = fetchMySourceMap(fileName);
		const sourcesRelativeTo = '< Relative path from source map file to source file. >';
		return map ? { map, sourcesRelativeTo } : null;	// Return null if no source map is found.
	}
});

The return object must be the same as source-map-resolve.

You can provide additional ignore patterns for the stack trace (on top the built in exclusion of jasmine sources), this is useful for when you are using test frameworks that show up in the stack trace like typemoq.

// regexp
new TSConsoleReporter({
	stackFilterIgnore: /node_modules\\typemoq/
});
// or glob
new TSConsoleReporter({
	stackFilterIgnore: '**/node_modules/typemoq/**'
});

You can provide additional filtering for the spec title, this is useful for when you want to limit or decorate the title output in some way.

new TSConsoleReporter({
	titleFilter: (title) => (title.length > 100) ? title.substr(0, 100 - 1) + '...' : title
});

You can provide additional filtering for the error message, this is useful for when you want to limit or decorate the message output in some way.

new TSConsoleReporter({
	messageFilter: (message) => message.split('\n')[0]
});
