Testing Frameworks for Ruby

This page serves as a knowledge source for understanding the different Testing Frameworks available for Ruby.

Introduction

There are a lot of testing tools that are available for Ruby language, they have different features and can be applied on different platforms. Here is a brief introduction and feature comparisons of popular testing frameworks. [EDIT NEEDED]

Unit Testing

Unit Testing is a method by which we can isolate and test a unit functionality of the program, typically individual methods during and long after the code is written.

Test::Unit

The in-built, ready to use unit testing mechanism for Ruby is called Test::Unit.It belongs to the XUnit family unit testing framework. It has a setup method for initialization, a teardown method for cleanup and the actual test methods itself. The tests are bundled separately in a test class in the code it is aimed to test.

Assertions

We can use Test::Unit to make assertions. The test is successful if the assertion is true and fails if the assertion is false.

assert( boolean, [message] )	True if boolean
assert_equal( expected, actual, [message] ) assert_not_equal( expected, actual, [message] )	True if expected == actual
assert_raise( Exception,... ) {block} assert_nothing_raised( Exception,...) {block}	True if the block raises (or doesn't) one of the listed exceptions.
