On the Add tasks screen, search for BlazeMeter and click the Add button on the BlazeMeter Integration.

Select Tasks

You have the following options under Select Tasks:

• Run Existing Performance Test

• Create Performance Test

• Create Multitest

Run Existing Performance Test

By default, Run Existing Performance Test is selected.

To run an existing test:

1. Enter your Test URL.
   1. To find your Test URL, log in to your BlazeMeter account.
   2. Click on Tests.
   3. Select the test you wish to use.

      Test details appear.

   4. Copy the URL of that page and paste it into the Test URL text box.

      

2. For the API Key and API Secret text box, default values will appear.
   Note: Azure DevOps supports the use of variables.
   • If you wish to create your own variables and store the API Key and API Secret values within those variables, you may leave the defaults. Refer to the next section on how to create variables in Azure DevOps.
   • Alternatively, you can clear the default values and configure the actual API Key and API Secret on the screen. For more information about key creation, see BlazeMeter API Keys to learn more about how to generate API Key and API Secret within BlazeMeter.

3. (Optional) Define a Report Name.

4. (Optional) For Do you want to update the test files before the test execution?, choose one of the following options:

   • No. This is the default.

   • Yes, I want to update main test files and its dependencies.

   • Yes, I want to update several test files using JSON.

5. (Optional) Enable Show Log if you want to see a running log of the test in the console.

6. (Optional) Enable Ignore SLA if you want the build to succeed regardless of the SLA.

7. Click Save.

8. Click Create Release.

9. Your release is ready.

10. Start your BlazeMeter test from the pipeline by clicking the Deploy button.

    

If you want to update main test files and dependencies to Run Existing Performance Test, you choose between "Yes, I want to update main test files and its dependencies" or "Yes, I want to update several test files using JSON".

If you select Yes, I want to update main test files and its dependencies:

1. Update the main test files by checking Update Main Test File. Then under Upload Test Script, upload the main test file.

   

2. If you want to upload dependencies as well, you have to check Upload Dependencies. Then under Upload Dependent Scripts you have to upload the dependencies.

   

Or, if you select Yes, I want to update several test files using JSON:

Upload the JSON file with content in the following format:

{
  "mainTestFile": "", // provide the main test file path
  "dependency" : "" // provide the dependency file path 
}

If you want to upload only the main test file, use the following syntax:

{
  "mainTestFile": "${maintest file path}",  
  "dependency" : ""
}

If you want to upload or update the dependency file, use the following syntax:

{
  "mainTestFile": "${maintest file path}",
  "dependency" : "${dependency File Path}"
}

Create Performance Test

If you want to create a performance test, select Create Performance Test.

1. For the API Key and API Secret text box, default values will appear.
   Azure DevOps supports the use of variables.
