Blisk is the browser that every web developer needs. Blisk is a Chromium-based browser that enables features that your regular browser cannot. You can see how your website or application work on different display resolution, you can prototype, test your product and get notified if there is a bug to fix.
Karate is the only open-source tool to combine API test-automation, mocks and performance-testing into a single, unified framework. The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers. Besides powerful JSON & XML assertions, you can run tests in parallel - which is critical for HTTP API testing.
