gulp-istanbul [![NPM version][npm-image]][npm-url] [![Build Status][travis-image]][travis-url] [![Dependency Status][depstat-image]][depstat-url]
===========================
[Istanbul][istanbul] unit test coverage plugin for [gulp][gulp].
Works on top of any Node.js unit test framework.
Installation
---------------
```shell
npm install --save-dev gulp-istanbul
```
Example
---------------
In your `gulpfile.js`:
#### Node.js testing
```javascript
var istanbul = require('gulp-istanbul');
// We'll use mocha in this example, but any test framework will work
var mocha = require('gulp-mocha');
gulp.task('pre-test', function () {
return gulp.src(['lib/**/*.js'])
// Covering files
.pipe(istanbul())
// Force `require` to return covered files
.pipe(istanbul.hookRequire());
});
gulp.task('test', ['pre-test'], function () {
return gulp.src(['test/*.js'])
.pipe(mocha())
// Creating the reports after tests ran
.pipe(istanbul.writeReports())
// Enforce a coverage of at least 90%
.pipe(istanbul.enforceThresholds({ thresholds: { global: 90 } }));
});
```
**Note:** Version 4.x.x of `gulp-mocha` is not supported (see issue [#115](https://github.com/SBoudrias/gulp-istanbul/issues/115) for details). In this example, you should use `gulp-mocha` version 3.0.1 for the time being.
#### Browser testing
For browser testing, you'll need to write the files covered by istanbul in a directory from where you'll serve these files to the browser running the test. You'll also need a way to extract the value of the [coverage variable](#coveragevariable) after the test have runned in the browser.
Browser testing is hard. If you're not sure what to do, then I suggest you take a look at [Karma test runner](http://karma-runner.github.io) - it has built-in coverage using Istanbul.
```javascript
var istanbul = require('gulp-istanbul');
gulp.task('pre-test', function () {
return gulp.src(['lib/**/*.js'])
// Covering files
.pipe(istanbul())
// Write the covered files to a temporary directory
.pipe(gulp.dest('test-tmp/'));
});
gulp.task('test', ['pre-test'], function () {
// Make sure your tests files are requiring files from the
// test-tmp/ directory
return gulp.src(['test/*.js'])
.pipe(testFramework())
// Creating the reports after tests ran
.pipe(istanbul.writeReports());
});
```
#### Source Maps
gulp-istanbul supports [gulp-sourcemaps][gulp-sourcemaps] when instrumenting:
```javascript
gulp.task('pre-test', function () {
return gulp.src(['lib/**/*.js'])
// optionally load existing source maps
.pipe(sourcemaps.init())
// Covering files
.pipe(istanbul())
.pipe(sourcemaps.write('.'))
// Write the covered files to a temporary directory
.pipe(gulp.dest('test-tmp/'));
});
```
API
--------------
### istanbul(opt)
Instrument files passed in the stream.
#### opt
Type: `Object` (optional)
```js
{
coverageVariable: 'someVariable',
...other Instrumeter options...
}
```
##### coverageVariable
Type: `String` (optional)
Default: `'$$cov_' + new Date().getTime() + '$$'`
The global variable istanbul uses to store coverage
See also:
- [istanbul coverageVariable][istanbul-coverage-variable]
- [SanboxedModule][sandboxed-module-coverage-variable]
##### includeUntested
Type: `Boolean` (optional)
Default: `false`
Flag to include test coverage of files that aren't `require`d by any tests
See also:
- [istanbul "0% coverage" issue](https://github.com/gotwarlost/istanbul/issues/112)
##### instrumenter
Type: `Instrumenter` (optional)
Default: `istanbul.Instrumenter`
Custom Instrumenter to be used instead of the default istanbul one.
```js
var isparta = require('isparta');
var istanbul = require('gulp-istanbul');
gulp.src('lib/**.js')
.pipe(istanbul({
// supports es6
instrumenter: isparta.Instrumenter
}));
```
See also:
- [isparta](https://github.com/douglasduteil/isparta)
##### Other Istanbul Instrumenter options
See:
- [istanbul Instrumenter documentation][istanbul-coverage-variable]
### istanbul.hookRequire()
Overwrite `require` so it returns the covered files. The method take an optional [option object](https://gotwarlost.github.io/istanbul/public/apidocs/classes/Hook.html#method_hookRequire).
Always use this option if you're running tests in Node.js
### istanbul.summarizeCoverage(opt)
get coverage summary details
#### opt
Type: `Object` (optional)
```js
{
coverageVariable: 'someVariable'
}
```
##### coverageVariable
Type: `String` (optional)
Default: `'$$cov_' + new Date().getTime() + '$$'`
The global variable istanbul uses to store coverage
See also:
- [istanbul coverageVariable][istanbul-coverage-variable]
- [SanboxedModule][sandboxed-module-coverage-variable]
#### returns
Type: `Object`
```js
{
lines: { total: 4, covered: 2, skipped: 0, pct: 50 },
statements: { total: 4, covered: 2, skipped: 0, pct: 50 },
functions: { total: 2, covered: 0, skipped: 0, pct: 0 },
branches: { total: 0, covered: 0, skipped: 0, pct: 100 }
}
```
See also:
- [istanbul utils.summarizeCoverage()][istanbul-summarize-coverage]
### istanbul.writeReports(opt)
Create the reports on stream end.
#### opt
Type: `Object` (optional)
```js
{
dir: './coverage',
reporters: [ 'lcov', 'json', 'text', 'text-summary', CustomReport ],
reportOpts: { dir: './coverage' },
coverageVariable: 'someVariable'
}
```
You can pass individual configuration to a reporter.
```js
{
dir: './coverage',
reporters: [ 'lcovonly', 'json', 'text', 'text-summary', CustomReport ],
reportOpts: {
lcov: {dir: 'lcovonly', file: 'lcov.info'}
json: {dir: 'json', file: 'converage.json'}
},
coverageVariable: 'someVariable'
}
```
##### dir
Type: `String` (optional)
Default: `./coverage`
The folder in which the reports are to be outputted.
##### reporters
Type: `Array` (optional)
Default: `[ 'lcov', 'json', 'text', 'text-summary' ]`
The list of available reporters:
- `clover`
- `cobertura`
- `html`
- `json`
- `lcov`
- `lcovonly`
- `none`
- `teamcity`
- `text`
- `text-summary`
You can also specify one or more custom reporter objects as items in the array. These will be automatically registered with istanbul.
See also `require('istanbul').Report.getReportList()`
##### reportOpts
Type: `Object` (optional)
```js
{
dir: './coverage'
}
```
You can also configure separate directory for each report.
```js
{
html: {
dir: './coverage/html',
watermarks: {
statements: [ 50, 80 ],
lines: [ 50, 80 ],
functions: [ 50, 80],
branches: [ 50, 80 ]
}
},
lcov: {dir: './coverage/lcov'},
lcovonly: {dir: './coverage/lcovonly'},
json: {dir: './coverage/json'},
}
```
`watermarks` can be used to confgure the color of the HTML report.
Default colors are.. RED: below 50% coverage, YELLOW: 50-80% coverage, GREEN: above 80%
##### coverageVariable
Type: `String` (optional)
Default: `'$$cov_' + new Date().getTime() + '$$'`
The global variable istanbul uses to store coverage
See also:
- [istanbul coverageVariable][istanbul-coverage-variable]
- [SanboxedModule][sandboxed-module-coverage-variable]
### istanbul.enforceThresholds(opt)
Checks coverage against minimum acceptable thresholds. Fails the build if any of the thresholds are not met.
#### opt
Type: `Object` (optional)
```js
{
coverageVariable: 'someVariable',
thresholds: {
global: 60,
each: -10
}
}
```
##### coverageVariable
Type: `String` (optional)
Default: `'$$cov_' + new Date().getTime() + '$$'`
The global variable istanbul uses to store coverage
##### thresholds
Type: `Object` (required)
Minimum acceptable coverage thresholds. Any coverage values lower than the specified threshold will fail the build.
Each threshold value can be:
- A positive number - used as a percentage
- A negative number - used as the maximum amount of coverage gaps
- A falsey value will skip the coverage
Thresholds can be specified across all files (`global`) or per file (`each`):
```
{
global: 80,
each: 60
}
```
You can also specify a value for each metric:
```
{
global: {
statements: 80,
branches: 90,
lines: 70,
functions: -10
}
each: {
statements: 100,
branches: 70,
lines: -20
}
}
```
#### emits
A plugin error in the stream if the coverage fails
