WebTau command line tool comes with a REPL mode that stands for 'read-eval-print-loop'. REPL is an established way to perform interactive execution of an API for the purpose of learning or experimenting. The REPL preserves the context of execution and each new command you run can rely on the established context.

To run WebTau in REPL mode run webtau repl webtau:000> 2 + 2 ===> 4 webtau:000> a = 5 ===> 5 webtau:000> a + 3 ===> 8

Use the REPL to try out various apis like http. , browser. , db. , cli. , etc. webtau:000> http.get("https://jsonplaceholder.typicode.com/todos/1") > executing HTTP GET https://jsonplaceholder.typicode.com/todos/1 . header.statusCode equals 200 (6ms) response (application/json; charset=utf-8): { "userId": 1, "id": 1, "title": "delectus aut autem", "completed": false } . executed HTTP GET https://jsonplaceholder.typicode.com/todos/1 (456ms)

Use cfg.url = "http://url" to set base url for experiments. webtau:000> cfg.url = "https://jsonplaceholder.typicode.com" > setting url source: "manual" url: "https://jsonplaceholder.typicode.com" . set url (0ms) "https://jsonplaceholder.typicode.com" webtau:000> http.get("/todos/1") > executing HTTP GET https://jsonplaceholder.typicode.com/todos/1 . header.statusCode equals 200 (1ms) response (application/json; charset=utf-8): { "userId": 1, "id": 1, "title": "delectus aut autem", "completed": false } . executed HTTP GET https://jsonplaceholder.typicode.com/todos/1 (52ms)

During browser testing the REPL preserves the context of an opened browser, so you can experiment with css selectors and element actions without re-opening the browser and setting the right web app state. webtau:000> browser.open("file:///home/runner/work/webtau/webtau/webtau-cli-testing/src/test/groovy/data/basic.html") > initializing webdriver for chrome . initialized webdriver for chrome (1s 0ms) > opening file:///home/runner/work/webtau/webtau/webtau-cli-testing/src/test/groovy/data/basic.html . opened file:///home/runner/work/webtau/webtau/webtau-cli-testing/src/test/groovy/data/basic.html (46ms) Using element selectors provides additional information in REPL mode to help with exploration webtau:000> $("p") found single element using by css p innerText: hello web page <p>hello web page</p>
