Test Steps
| Step No. | Step Description | Expected Result |
|---|---|---|
| 1 | Open JMeter | JMeter should open |
| 2 | Right click on 'Test Plan' and add a thread group (Add > Threads (Users) > Thread Group) | Thread group should appear under test plan |
| 3 | Change 'Number of Threads (users)' and 'Ramp-up period (seconds)' | The higher the users to seconds ratio, the bigger the load |
| 4 | Right click on the thread group and add a HTTP request (Add > Sampler > HTTP Request) | An HTTP Request should appear under the thread group |
| 5 | Change 'Server Name or IP' to 'localhost', 'Port Number' to '3001', Path to '/api-docs', and 'Name' to something appropriate like 'Documentation' | This makes the JMeter GET localhost:3001/api-docs |
| 6 | Right click the previous HTTP request and duplicate it | There should be another HTTP request of the same name under the thread group |
| 7 | Change the name to 'Statinos' and path to /stations | This tells the thread group to fetch all the stations |
| 8 | Duplicate an HTTP request again | Another HTTP request should appear under the thread group |
| 9 | Change the path of the new HTTP request to '/stations/24607?includeSensors=true' and rename the HTTP request to 24607 | This tells the thread group to GET station with the station ID '24607' |
| 10 | Right click on 'Thread Group and add 'View Results Tree' (Add > Listener > View Results Tree) | 'View Results Tree' appears under the thread group |
| 11 | Hit 'Start' | All the thread groups appear under 'View Results Tree' as many times as there were users, and have a green check mark next to them signifying that the tests passed |
To be taken into account during the test
- Load testing can put a significant load on your server, so make sure you perform these tests in a controlled environment and avoid testing on production systems without proper planning.
Test Result (Pass/Fail Criteria)
- PASS condition: The 'View Results Tree' shows all users with all green check marks
- FAIL condition: Pass condition is not fulfilled
