## Overview
|
|
|
|
MSpec is a specialized framework that is syntax-compatible with RSpec for
|
|
basic things like 'describe', 'it' blocks and 'before', 'after' actions. MSpec
|
|
contains additional features that assist in writing the RubySpecs used by
|
|
multiple Ruby implementations.
|
|
|
|
MSpec attempts to use the simplest Ruby language features so that beginning
|
|
Ruby implementations can run the Ruby specs.
|
|
|
|
MSpec is not intended as a replacement for RSpec. MSpec attempts to provide a
|
|
subset of RSpec's features in some cases and a superset in others. It does not
|
|
provide all the matchers, for instance.
|
|
|
|
However, MSpec provides several extensions to facilitate writing the Ruby
|
|
specs in a manner compatible with multiple Ruby implementations.
|
|
|
|
1. MSpec offers a set of guards to control execution of the specs. These
|
|
guards not only enable or disable execution but also annotate the specs
|
|
with additional information about why they are run or not run.
|
|
|
|
2. MSpec provides a different shared spec implementation specifically
|
|
designed to ease writing specs for the numerous aliased methods in Ruby.
|
|
The MSpec shared spec implementation should not conflict with RSpec's own
|
|
shared behavior facility.
|
|
|
|
3. MSpec provides various helper methods to simplify some specs, for
|
|
example, creating temporary file names.
|
|
|
|
4. MSpec has several specialized runner scripts that includes a
|
|
configuration facility with a default project file and user-specific
|
|
overrides.
|
|
|
|
## Requirements
|
|
|
|
MSpec requires Ruby 2.2 or more recent.
|
|
|
|
## Bundler
|
|
|
|
A Gemfile is provided. Use Bundler to install gem dependencies. To install
|
|
Bundler, run the following:
|
|
|
|
```bash
|
|
gem install bundler
|
|
```
|
|
|
|
To install the gem dependencies with Bundler, run the following:
|
|
|
|
```bash
|
|
ruby -S bundle install
|
|
```
|
|
|
|
## Running Specs
|
|
|
|
Use RSpec to run the MSpec specs. There are no plans currently to make the
|
|
MSpec specs runnable by MSpec.
|
|
|
|
After installing the gem dependencies, the specs can be run as follows:
|
|
|
|
```bash
|
|
ruby -S bundle exec rspec
|
|
```
|
|
|
|
Or
|
|
|
|
```bash
|
|
ruby -S rake
|
|
```
|
|
|
|
To run an individual spec file, use the following example:
|
|
|
|
```bash
|
|
ruby -S bundle exec rspec spec/helpers/ruby_exe_spec.rb
|
|
```
