Traffic Router Tests

Load Test

You can simulate a mix of HTTP and HTTPS traffic for a CDN by choosing the number of HTTP delivery services and the number HTTPS delivery services the test will exercise.

There are 2 parts to the load test.

• A web server that makes the actual requests and takes commands to fetch data from the CDN, start the test, and return current results.
• A web page that's used to run the test and see the results.

Running the Load Test

2. The web server is a go program, set your GOPATH env variable appropriately
3. Open a terminal program and navigate to the traffic_control/test/router/server directory
4. execute the command go run server.go
5. Open the file traffic_control/test/router/index.html
6. Authenticate against a Traffic Ops host, should be an instantaneous operation, you can watch the output from server.go for feedback
7. Enter the Traffic Ops host in the second form and click the button to get a list of CDN's
8. Wait for the web page to show a list of CDN's under the above form, this may take several seconds
9. The List of CDN's will display the number of Http and Https capable delivery services that may be exercised
10. Choose the CDN you want to exercise from the dropdown
11. Fill out the rest of the form, enter appropriate numbers for each http and https delivery services
