Mocha param
Parameterized tests for Mocha.
npm install --save-dev mocha-param
New in Version 2.0.0
- The tested value can now be included in the description for each test.
- Optionally use require('mocha-param') rather than require('mocha-param').itParam;
Basic Usage
Simply use 'itParam' instead of the standard mocha 'it' function and pass in an array of data.
var itParam = ;// We have used chai as an assertion library but you can use any.var expect = expect; // A Simple sync example taking an array as a parameter.// 'value' is each value in the array
Result:
basic mocha test with data
✓ test value is a number
✓ test value is a number
✓ test value is a number
3 passing (25ms)
Add the values being tested into the test descriptions
To display the values being passed into your tests, use "${value}" as part of the test description.
Result:
basic mocha test with data
✓ test value 1 is a number
✓ test value 2 is a number
✓ test value 3 is a number
3 passing (25ms)
Async
Standard async mocha tests take a 'done' parameter which is called when execution is finished. mocha-param works the same.
// A Simple async example taking an array and calling done()// 'value' each value in the array// 'done' is the standard mocha done callback
Result:
async mocha test with data
✓ test value 1 is a number
✓ test value 2 is a number
✓ test value 3 is a number
3 passing (17ms)
Array Objects
The array can contain anything that you like. Nested values to be displayed in the test description can be accessed with ${value.<property>}
var myData = name: 'rob' age: 23 name: 'sally' age: 29 ;
Result:
test that person objects are older than 20
✓ test person rob (age 23) in the array
✓ test person sally (age 29) in the array
2 passing (14ms)
