# PEG.js Test Suites |
|||
|
|||
This directory contains various test suites and scripts to ensure PEG.js works correctly. |
|||
|
|||
* [Spec Suite](spec): Runs various test's that ensure PEG.js and it's generated parsers are working as intended. All tests should always pass on all supported platforms. |
|||
* [Benchmark Suite](benchmark): It measures speed of the parsers generated by PEG.js on various inputs. Its main goal is to provide data for code generator optimizations. |
|||
* [Impact Script](impact): Measures impact of a Git commit (or multiple commits) on generated parsers speed and size. |
|||
|
|||
## Download and Install |
|||
|
|||
To run the PEG.js test suites you most download the and install the module via the git repository: |
|||
|
|||
1. Make sure you have Node.js and Git installed. |
|||
|
|||
2. Download via Git and change the currently working directory: |
|||
|
|||
```console |
|||
$ git clone https://github.com/pegjs/pegjs.git |
|||
$ cd pegjs |
|||
``` |
|||
|
|||
3. Install all dependencies, including the development dependencies: |
|||
|
|||
```console |
|||
$ npm install |
|||
``` |
|||
|
|||
4. Install Gulp globally: |
|||
|
|||
```console |
|||
$ npm install gulp -g |
|||
``` |
|||
|

|
|||
## Running in Node.js |
|||
|
|||
The commands below need to be executed via the console from the PEG.js root directory (one level up from this one), after which they will output their results (if any). |
|||
|
|||
* Execute source code linting: |
|||
|
|||
```console |
|||
$ gulp lint |
|||
``` |
|||
|
|||
* Execute the spec test suite: |
|||
|
|||
```console |
|||
$ gulp test |
|||
``` |
|||
|
|||
* Execute the benchmark suite: |
|||
|
|||
```console |
|||
$ gulp benchmark |
|||
``` |
|||
|
|||
* Execute the impact suite: |
|||
|
|||
```console |
|||
$ node test/impact |
|||
``` |
|||
|
|||
## Running in the Browser |
|||
|
|||
1. Serve the test suites using a web server: |
|||
|
|||
```console |
|||
$ node test/server/run |
|||
``` |
|||
|
|||
2. Point your browser to the [test suite](http://localhost:8000/) |
