Headless tape test runner
npm install tape-runA tape test runner that runs your tests in
a (headless) browser and returns 0/1 as exit code, so you can use it as yournpm test script.
First write a test utilizing tape and save
it to test/test.js:
``js
var test = require('tape');
test('a test', function (t) {
t.ok(true);
t.end();
});
`
Then run this command using tape-run and
browserify and watch the magic happen
as the TAP results stream in from a browser (default: electron):
`bash
$ browserify test/*.js | tape-run
TAP version 13one
ok 1 true
1..1
$ echo $?
0
`
In simple cases you can run rollup and tape-run right from command line:`bash`
$ rollup test/test.js -f iife | tape-run
If you want to use a configuration file, here's an example for :`js
import resolve from 'rollup-plugin-node-resolve';
import commonjs from 'rollup-plugin-commonjs';
import builtins from 'rollup-plugin-node-builtins';
import istanbul from 'rollup-plugin-istanbul';
export default {
input: 'test/test.js',
output: { format: 'iife', sourcemap: 'inline' },
plugins: [
resolve(),
commonjs(),
builtins(),
istanbul({ exclude: ['dist'] })
]
}
`
To use with webpack, set up a webpack.test.config.js to bundle your tape tests. Then, include webpack-tape-run plugin in it. As a result, $ webpack --config webpack.test.config.js builds your tests with webpack, runs them in a headless browser, and outputs tap into console with correct exit code. Neat!
You can use tape-run from JavaScript too:
`js
var run = require('tape-run');
var browserify = require('browserify');
browserify(__dirname + '/test/test.js')
.bundle()
.pipe(run())
.on('results', console.log)
.pipe(process.stdout);
`
And run it:
`bash
$ node example/api.js
TAP version 13one
ok 1 true
1..1
$3
can be:*
wait (Number) [Default: 1000]: Make tap-finished wait longer for results.
Increase this value if tests finish without all tests being run.
* port (Number): If you specify a port it will wait for you to open a browser
on http://localhost: and tests will be run there.
* static (String): Serve static files from this directory.
* browser (String): Browser to use. Defaults to electron. Available if installed:
* chrome
*
*
*
*
* : Leave the browser open for debugging after running tests.
* node (Boolean) Enable nodejs integration for electron.
* sandbox (Boolean) [Default: true]: Enable electron sandbox.
* basedir (String): Set this if you need to require node modules in node mode.The CLI takes the same arguments, plus
--render (see blow):`bash
$ tape-run --help
Pipe a browserify stream into this.
browserify [opts] [files] | tape-run [opts]Options:
--wait Timeout for tap-finished
--port Wait to be opened by a browser on that port
--static Serve static files from this directory
--browser Browser to use. Always available: electron. Available if installed: chrome, firefox, ie, phantom, safari [default: "electron"]
--render Command to pipe tap output to for custom rendering
--keep-open Leave the browser open for debugging after running tests
--node Enable nodejs integration for electron
--sandbox Enable electron sandbox [default: true]
--basedir Set this if you need to require node modules in node mode
--help Print usage instructions
`...or any of the other options you can pass to browser-run.
Custom Rendering
In order to apply custom transformations to tap output without sacrificing the proper exit code, pass
with a command like tap-spec:`bash
$ browserify test.js | tape-run --render="tap-spec" one
✔ true
`Headless testing
In environments without a screen, you can use
to simulate one. We recommend using the default electron browser,
which however requires you to add additional parts to your headless configurations.$3
This is a full example to run
npm test. Refer to the last 2 lines in the YAML config:`yml
on:
- pull_request
- pushjobs:
test:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v1
- run: npm install
- run: sudo apt-get install xvfb
- run: xvfb-run --auto-servernum npm test
`$3
Add this to your travis.yml:
yml
addons:
apt:
packages:
- xvfb
install:
- export DISPLAY=':99.0'
- Xvfb :99 -screen 0 1024x768x24 > /dev/null 2>&1 &
- npm install
`$3
bash
$ sudo apt-get install xvfb # or equivalent
$ export DISPLAY=':99.0'
$ Xvfb :99 -screen 0 1024x768x24 > /dev/null 2>&1 &
$ browser-run ...
`$3
There is also an example Docker image. Source
Installation
With npm do
bash
$ npm install tape-run -g # for cli
$ npm install tape-run # for api
