GitLab

GitLab CI

GitLab CI is a tool to automatically build your software through continuous deployment. GitLab CI is nothing else than an command-line runner built which runs your own scripts inside Docker containers.

OctoPerf seamlessly integrates with GitLab CI thanks to our Maven Plugin. You can run OctoPerf load tests as part of your software builds like:

  • Run an existing scenario,
  • Import and run a JMeter JMX stored in your git repository,
  • Or even stop the build automatically whenever a threshold or SLA exceeds a certain criticity (Example: WARNING).

Setup

Prerequisites

In order to setup gitlab builds to run OctoPerf load tests, first you need:

Introduction

GitLab Repo

First, you need to:

  • Create a GitLab account,
  • Then create a new repository named octoperf-ci.

Next, you will need an OctoPerf Account. Now, let's setup a dummy project:

  • Create a new project named GitLab in your Default workspace,
  • Import the sample JMX. This should create an httpbin.org virtual user,
  • Create a Scenario named Scenario and configure the load settings for the httpbin.org user.

Now, it's time to save your API key for further use:

  • Click in the top-right corner in OctoPerf UI and choose Profile in the menu,
  • Copy the API Key.

Let's setup the gitlab repository now

GitLab Repository

GitLab CI easily supports running Maven builds:

  • First, clone the gitlab repository:
git clone git@gitlab.com:username/octoperf-ci.git
  • Then, you should create the maven pom.xml config file which contains:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <packaging>pom</packaging>
  <groupId>com.octoperf</groupId>
  <artifactId>octoperf-test</artifactId>
  <version>1.0.0-SNAPSHOT</version>

  <build>
    <plugins>
      <plugin>
        <groupId>com.octoperf</groupId>
        <artifactId>octoperf-maven-plugin</artifactId>
        <version>2.0.0</version>
        <configuration>
          <apiKey>YOUR_API_KEY</apiKey>
          <workspaceName>Default</workspaceName>
          <projectName>GitLab</projectName>
          <scenarioName>Scenario</scenarioName>
        </configuration>
      </plugin>
    </plugins>
  </build>

  <pluginRepositories>
    <pluginRepository>
      <id>octoperf-releases</id>
      <name>OctoPerf Releases</name>
      <url>https://github.com/octoperf/maven-repository/raw/master/releases</url>
    </pluginRepository>
    <pluginRepository>
      <id>octoperf-snapshots</id>
      <name>OctoPerf Snapshots</name>
      <url>https://github.com/octoperf/maven-repository/raw/master/snapshots</url>
    </pluginRepository>
  </pluginRepositories>
</project>

Make sure to replace YOUR_API_KEY by your account API Key.

  • Then, create a .gitlab-ci.yml file at the root of your project:
image: maven:latest

cache:
  paths:
    - .m2/repository/
    - target/

test:
  stage: test
  when: manual
  script:
    - mvn octoperf:execute-scenario

This will execute an existing scenario named Scenario, expected to be in your account GitLab project and Default workspace.

  • Commit those changes to your repository:
git add -A && git commit && git push

Which will push the 2 files to your git repository:

  • The CI Job should now be visible on GitLab,

GitLab Job

  • Now click on Run Pipeline to trigger a new build. After a while, the test should start:

GitLab Build Running

Congratulations! You've just triggered a load test on OctoPerf using GitLab CI and OctoPerf Maven Plugin.
