Component Pascal vs. Crystal vs. Python vs. TestMace Comparison Chart

Crystal’s syntax is heavily inspired by Ruby’s, so it feels natural to read and easy to write, and has the added benefit of a lower learning curve for experienced Ruby devs. Crystal is statically type-checked, so any type errors will be caught early by the compiler rather than fail on runtime. Moreover, and to keep the language clean, Crystal has built-in type inference, so most type annotations are unneeded. All types are non-nilable in Crystal, and available variables are represented as a union between the type and nil. As a consequence, the compiler will automatically check for null references in compile time. Crystal’s answer to metaprogramming is a powerful macro system, which ranges from basic templating and AST inspection to types inspection and running arbitrary external programs.

Test Mace is a modern powerful crossplatform tool for working with an API and creating automated API tests. Create requests and scenarios using variables, authentication, autocomplete feature and syntax highlighting. Build complex scenarios using our convenient and simple UI interface. Perform full regression testing with just one click. Assign a request result to a variable and get access from other nodes. Save authorization tokens, response headers or parts of a response body. Run your scenarios in different environment contexts. Use this to organize development, stage and production environments. Embedded authentication methods will help you to do authentication if you use one of the most popular types. You can use quick share feature to share your request with colleagues. Just press a button to copy a specific node's url. All that you need now is to send this url to your teammate.
