testling
Run testling-ci tests locally.
example
write a test:
var test = require('tape');
test('beep boop', function (t) {
t.plan(2);
t.equal(1+1, 2);
t.ok(true);
});
run your test in a local headless browser:
$ browserify example/test.js | testling
TAP version 13
# beep boop
ok 1 should be equal
ok 2 (unnamed assert)
1..2
# tests 2
# pass 2
# ok
with an exit code of 0 for successes and non-zero for failures like a good unix citizen
Once you have a package.json
with a configured "testling"
field, you can just
type:
$ testling
to run all your tests locally just like they will be run on testling-ci. This includes mocha harnesses, scripts, and files parameters.
usage
usage: testling {DIRECTORY|-} {OPTIONS}
If there (is no DIRECTORY and stdin is a tty) or the DIRECTORY is "-",
javascript will be read from stdin and executed.
Otherwise, DIRECTORY (or the $CWD) will be checked for a package.json with a
testling field.
OPTIONS are:
--html Instead of launching a server, show the generated html.
--no-show Don't render the console.log() output to the document body.
-u Instead of launching a browser, print the url to visit so you can
open the browser yourself.
-x Launch a browser with an explicit command. By default, chrome or
firefox is launched by searching your $PATH.
--host Set up the testling url on a specific hostname. Default: localhost
--port Set up the testling url on a specific port

code coverage
To compute code coverage, just use the
coverify
transform with -t coverify
when you run browserify.
coverify writes coverage data with
console.log(), so you can pipe the output of testling through to the coverify
command to parse the results and give human-readable output:
$ browserify -t coverify test.js | testling | coverify
TAP version 13
# beep boop
ok 1 should be equal
1..1
# tests 1
# pass 1
# ok
# /home/substack/projects/coverify/example/test.js: line 7, column 16-28
if (err) deadCode();
^^^^^^^^^^^
# /home/substack/projects/coverify/example/foo.js: line 3, column 35-48
if (i++ === 10 || (false && neverFires())) {
^^^^^^^^^^^^
The exit code of coverify is non-zero when there are unreachable expressions.
dependencies
Make sure you have PhantomJS installed; this is the headless browser that testling will run your tests in if you are not using the -u
option.
install
First, install browserify
globally so that the testling
command can find it
when there is no browserify
in ./node_modules/.bin
:
npm install -g browserify
then do:
npm install -g testling
