AppSuite:Load Tests
Software Requirements
- Java SE JDK6 or JDK7
- Git
- SBT
Getting Performance Repository
- Cloning Repository
$ git clone https://git.open-xchange.com/git/wd/testing/performance
- Checkout a branch, e.g. develop
$ git checkout develop
Install SBT
Since we use the Gatling-SBT plugin, which allows us to use Gatling as a testing framework, we'll need to install SBT first.
Installing sbt on Mac
$ port install sbt
$ brew install sbt
Installing sbt on Windows
- Download the msi installer and install it.
Installing sbt on Linux
Installing sbt manually
- Manual instructions
Build and execute the tests with the SBT-Plugin
After SBT has been successfully installed we can switch to the project's directory:
$ cd ~/performance/com.openexchange.test.performance.gatling
SBT can be used both as a command line script and as a build console. Most of the commands can be run standalone by passing the command as an argument to SBT, e.g.
$ sbt update
Note that if a command takes arguments, you need to quote the entire argument path, e.g.
$ sbt 'gatling:testOnly com.openexchange.test.performance.gatling.tests.QAPerfOX6'
Development Environment
If you want to execute the tests via an IDE like Eclipse or IntelliJ IDEA then you will also need to install the following software:
- Eclipse 4.2 or later
- Scala IDE plugin
Importing Project into Eclipse
- Open Eclipse
- Click on File → Import... → Maven → Existing Maven Project
- Select the gatling folder within the performance repository
Configurable Parameters
List of all available System-Properties and JVM-Arguments:
- protocol
- Which protocol to use. Possible values are: "http" or "https". Default value: "http".
- host
- Which host to use. Possible values are: "localhost", "10.0.0.1" or if you want to stress several groupware servers, to bypass a loadbalancer for example, then you can use comma-separated IPs or hostnames "10.0.0.1,10.0.0.2,localhost". Default value: "localhost".
- users
- How many concurrent users to simulate. Default value: "5".
- durationTime
- Duration time of the simulation. Default value: "30".
- durationUnit
- The Unit of the durationTime. Possible values are: "SECONDS", "MINUTES", "HOURS" or "DAYS". Default value: "SECONDS".
- successpercent
- Successful responses in percentage. Default value: "100".
- reqpersec
- Mean number of requests per second (lower bound). Default value: "0".
- resptime
- Mean response time (lower bound). Default value: "0".
- csv_users
- Name of the CSV-File for feeding the requests. Default value: "ox_user_credentials.csv".
- syncmsgmax
- How many objects to synchronize. Relevant only for QAPerfUSM. Default value: "50".
- pimObjects
- How many PIM Objects, e.g. contacts, should be created. Default value: "5".
Test Execution
Pre-Requisites for the Open-Xchange Groupware Server
Disabling rate limitation
- Modify the parameter maxRateLenientClients @server.properties:
$ vim /opt/etc/open-xchange/etc/server.properties
- Specify a new User-Agent which is excluded from rate limit checks
"GATLING*"
Resources/Data
In the data folder you can find an sample csv file which is used to perform a login. If you want to use your own CSV-File place it into the data directory.
- Structure of the csv file:
username,password
user1,secret
user2,secret
user3,secret
...
user998,secret
user999,secret
user1000,secret
Practical hints and tips
- If you want to run tests for more than 24h, uncomment the "timeOut" → "simulation" property at gatling.conf and define a value of more than 24h (in seconds).
- If you experience OutOfMemory issues when generating charts, adjust "charting" → "accuracy" to a higher value. This will lower the accuracy of the generated graphs. Especially for long-running tests, this could be set to 100ms.
