Installation

PHP Version >= 5.4 is required!

The following instructions outline installation using Composer. If you don't have Composer, you can download it from http://getcomposer.org/

Mocking Examples

Basic mocking example, if a function wasn't stubbed the return value will always be NULL.

Stubbing

The when function is used to stubbing methods with specific parameters, following a throws, returns or a callback action.

Methods:

• throws($exception) - Throws an exception
• returns($response) - Returns a $response
• callback(function() { /*...*/ }) - Calling a callback

Partial Mock

partial mock is used when you need some of the methods to behave normally except from that one method you need to test. that can be done with partial mock, it keeps the logic unless you stub the method.

Stubbing Method Chaining

when function is also used to stub chained methods, follows the same actions as the single function stubbing return, throw or callback.

Verifying

Once created, mock will remember all invocations. Then you can selectively verify some interaction you are inserted in.

Methods:

• atLeast($times) - Verify called at least $times
• atLeastOnce() - Alias of atLeast(1)
• calledTimes($times) - Verify called exactly $times
• neverCalled() - Alias of calledTimes(0)
• lessThan($times) - Verify called less than $times

Argument Matcher

ShortifyPunit allows the use of Hamcrest PHP (https://github.com/hamcrest/hamcrest-php) matcher on any argument. Hamcrest is a library of "matching functions" that, given a value, return true if that value matches some rule.

Hamcrest matchers are included by default.

Examples:

Some common Hamcrest matchers:

• Core
  • anything - always matches, useful if you don't care what the object under test is
• Logical
  • allOf - matches if all matchers match, short circuits (like PHP &&)
  • anyOf - matches if any matchers match, short circuits (like PHP ||)
  • not - matches if the wrapped matcher doesn't match and vice versa
• Object
  • equalTo - test object equality using the == operator
  • anInstanceOf - test type
  • notNullValue, nullValue - test for null
• Number
  • closeTo - test floating point values are close to a given value
  • greaterThan, greaterThanOrEqualTo, lessThan, lessThanOrEqualTo - test ordering
• Text
  • equalToIgnoringCase - test string equality ignoring case
  • equalToIgnoringWhiteSpace - test string equality ignoring differences in runs of whitespace
  • containsString, endsWith, startsWith - test string matching
