BlazeMeter and Jenkins can be integrated for continuous testing in a CI/CD pipeline. First, install the BlazeMeter plugin on Jenkins. Then, create a new Jenkins job or project. In the build section of the job configuration page, add a BlazeMeter test by selecting “Add Build Step” then “Run BlazeMeter Test”. Input your BlazeMeter API key and select the desired test from your BlazeMeter account. Configure post-build actions to determine how Jenkins should react based on the results of the BlazeMeter tests. For instance, you may want Jenkins to fail the build if the BlazeMeter test fails. This setup allows automated performance testing every time code is pushed, ensuring that any performance degradation is caught immediately.
