Tslint-teamcity-reporter NPM

tslint-teamcity-reporter

A TSLint formatter/reporter for use in TeamCity which groups by files using TeamCity Test Suite

Note: v3.0.0 is completely rewritten to keep it more maintainable (borrowing from eslint-teamcity and tslint internal tests), and will be a breaking change to your configuration and output.

Changes

From the CLI, the formatter can now be specified as -t ./node_modules/tslint-teamcity-reporter/index.js
The lint errors reported as tests are now grouped by file
- This means that on the top-level, you only see failed files, not individual errors
- The individual errors are now displayed as error output for each file
- This means that the 'failed test count' will drop significantly, please take into account in your overall metrics
- If you liked the old approach better, please let me know in a ticket, and I can add it back as an option
Warnings are now treated as such, will show up in the logs and at the bottom of a failed test

Installation

yarn add tslint-teamcity-reporter

npm i -D tslint-teamcity-reporter

Usage

Use it with:

TSLint CLI

tslint files/**/*.ts -t ./node_modules/tslint-teamcity-reporter/index.js

grunt-tslint

module.exports = grunt => {
  grunt.loadNpmTasks('grunt-tslint');

  grunt.initConfig({
    tslint: {
      options: {
        configuration: './tslint.json',
        formatter: 'tslint-teamcity-reporter',
      },
      files: {
        src: ['**/*.ts'],
      },
    },
  });

  grunt.registerTask('default', ['tslint']);
};

gulp-tslint

const gulp = require('gulp');
const tslint = require('gulp-tslint');

gulp.task('tslint', () =>
  gulp
    .src('**/*.ts')
    .pipe(
      tslint({
        configuration: './tslint.json',
        formatter: 'tslint-teamcity-reporter',
        formattersDirectory: 'anything-but-falsy', // passing a falsy value will resolve in `null` and throw an error in tslint
      }),
    )
    .pipe(tslint.report()),
);

gulp.task('default', ['tslint']);

Configuration

There are several ways that you can configure tslint-teamcity. You don't have to configure anything by default, you just have the option to if you would like. Settings are looked for in the following priority:

1. As a second argument

If you run tslint-teamcity-reporter by requiring it in your code, you can pass a second argument to the function:

import { Formatter } from 'tslint-teamcity-reporter';

const formatter = new Formatter();
const options = {
  reporter: 'inspections',
  reportName: 'My TSLint Violations',
  errorStatisticsName: 'My TSLint Error Count',
  warningStatisticsName: 'My TSLint Warning Count',
};
console.log(formatter.format(tslintFailures, options));

2. From your package.json

If you have a package.json file in the current directory, you can add an extra "tslint-teamcity-reporter" property to it:

{
  "tslint-teamcity-reporter": {
    "reporter": "inspections",
    "report-name": "My TSLint Violations",
    "error-statistics-name": "My TSLint Error Count",
    "warning-statistics-name": "My TSLint Warning Count"
  }
}

3. ENV variables

export TSLINT_TEAMCITY_REPORTER="inspections"
export TSLINT_TEAMCITY_REPORT_NAME="My Formatting Problems"
export TSLINT_TEAMCITY_ERROR_STATISTICS_NAME="My Error Count"
export TSLINT_TEAMCITY_WARNING_STATISTICS_NAME="My Warning Count"

You can also output your current settings to the log if you set:

export TSLINT_TEAMCITY_DISPLAY_CONFIG=true

Output type

By default, the output is displayed as tests on a TeamCity build ("reporter": "errors"). You can change it to be displayed as "Inspections" in a separate tab by setting the "reporter": "inspections" option.

Building

In order to build tslint-teamcity-reporter, ensure that you have Git and Node.js installed.

Install dev dependencies:

yarn

Use one of the following main scripts:

yarn build            # build this project
yarn dev              # run compilers in watch mode, both for babel and typescript
yarn test             # run the unit tests incl coverage
yarn test:dev         # run the unit tests in watch mode
yarn lint             # run eslint and tslint on this project

When installing this module, it adds a pre-commit hook, that runs lint and prettier commands before committing, so you can be sure that everything checks out.
