Example
-------
```js
// Load test runner and your app
var doTest = require ('dotest');
var app = require ('./');
// Check app interface
doTest.add ('App interface', function (test) {
test ()
.isFunction ('fail', 'methodOne', app.methodOne)
.isObject ('fail', 'sub', app.sub)
.isFunction ('fail', 'sub.methodTwo', app.sub.methodTwo)
.done ();
});
// Check method response
doTest.add ('App methodOne', function (test) {
app.methodOne (function (err, data) {
test (err)
.isObject ('fail', 'Callback data', data)
.isArray ('fail', 'data.music', data.music)
.isNotEmpty ('warn', 'data.music', data.music)
.done ();
});
});
// Run the tests
doTest.run ();
```
Installation
------------
This is usually intended for CI builds,
so best to make sure it's in your dev dependencies ;)
`npm install dotest --save-dev`
Configuration
-------------
The script takes these env variables.
They override the code settings.
name | default | description
:-----------|:--------|:-----------------------------------------
DOTEST_WAIT | 0 | Pause between tests, in ms (1000 = 1 sec)
.add
----
**( label, testFunction )**
Add a new test to the queue.
```js
doTest.add ('App interface', function (test) {
test ()
.isArray ('fail', 'my array', [])
.done ();
});
```
.run
----
**( [wait] )**
Run the tests from the queue, one by one.
param | type | required | default | description
:-----|:-------|:---------|:--------|:--------------------------------------------
wait | number | no | 0 | Wait time between tests in ms (1000 = 1 sec)
```js
// Normal, without pause between tests
doTest.run ();
// Or wait 2 seconds
doTest.run (2000);
```
.log
----
**( [type], str )**
Fancy `console.log` with style.
param | type | required | default | description
:-----|:-------|:---------|:--------|:------------------------------
type | string | no | plain | Text style to apply, see below
str | string | yes | | The string to output
style | description
:-----|:------------------------------------
fail | `FAIL Text` with _FAIL_ in red
good | `good Text` with _good_ in green
warn | `warn Text` with _warn_ in yellow
info | `info Text` with _info_ in cyan
note | `Text` with _Text_ in bold
error | `ERROR Error.message\nError\nError.stack` with _ERROR_ in red
plain | No styling
The styles `error`, `fail` and `warn` add to the _errors_ and _warnings_ counters,
where `error` and `fail` also cause the script to fail.
```js
// Bold text
doTest.log ('note', 'Hello world');
```
.exit
-----
**( )**
Force exit the process, after writing statistics to the console.
```js
doTest.exit ();
```
.test
-----
**( [err] )**
Returns check functions.
Optionally test for `err` instance of `Error` and dump it to the console.
The check functions take a `level` parameter.
When set to `fail` the check reports _fail_ and the whole test script will eventually fail.
When set to `warn` the check reports _warn_ but won't cause the script to fail.
You can concat the check functions for clean code.
```js
// Using the method
doTest.add ('App interface', function () {
doTest.test ()
.isObject ('fail', 'Callback data', data)
.done ();
});
// Or using the shortcut
doTest.add ('App interface', function (test) {
test ()
.isObject ('fail', 'Callback data', data)
.done ();
});
```
test() .done
------------
**( [callback] )**
Run the next test from the queue.
Optionally run a `callback` function before the next test.
See example above.
test() .exit
------------
**( )**
Alias to [dotest.exit()](#exit).
Works similar to `.done()` where it ends the test,
but `.exit()` also ends the whole script.
```js
test ()
.isArray ('fail', 'data', [])
.exit ();
```
test() .info
------------
**( message )**
Output 'info' log line.
The `message` can be of any type.
When it is not a string, the type is written instead
and the full value of `message` dumped right below.
```js
test ()
.info ({ hello: 'world' })
.done ();
// Output:
// info Object
// { hello: 'world' }
```
test() .good
------------
**( message )**
Output 'good' log line.
The `message` can be of any type.
When it is not a string, the type is written instead
and the full value of `message` dumped right below.
```js
test ()
.good ('It works great')
.done ();
// Output:
// good It works great
```
test() .warn
------------
**( message )**
Output 'warn' log line.
The `message` can be of any type.
When it is not a string, the type is written instead
and the full value of `message` dumped right below.
```js
test ()
.warn ('Hmm something odd happened')
.done ();
// Output:
// warn Hmm something odd happend
```
test() .fail
------------
**( message )**
Output 'FAIL' log line.
The `message` can be of any type.
When it is not a string, the type is written instead
and the full value of `message` dumped right below.
```js
test ()
.fail ('We have a problem')
.done ();
// Output:
// FAIL We have a problem
```
test() .error
-------------
**( err )**
Output 'ERROR' log line with dump and stack trace.
```js
var err = new Error ('Oops');
test ()
.error (err)
.done ();
// Output:
// ERROR Oops
//
// [Error: Oops]
// ...
```
