When we write a spring rest controller we give version url and start writing different functions as endpoints like below @RestController @RequestMapping("/api/v1") public class ControllerApi { final LoginSender loginSender; public ControllerApi(LoginSender loginSender) { this.loginSender = loginSender; } @PostMapping("/login") boolean login(@RequestBody LoginParams params) { return loginSender.login(params.server(), params.login(), params.password(), params.build(), params.webManager()); } @GetMapping("/get1") LoginParams get1(@RequestParam String login, @RequestParam(required = false) String webMan, @RequestParam(required = false) String server, @RequestParam(required = false) String pass, @RequestParam(required = false) String build) { return LoginParams.builder() .webManager(webMan) .server(server) .password(pass) .login(login) .build(build) .build(); } } ib the future this controller will have different version number from v1 to v2 or in the future someone will change login endpoint from “/login” to “/loginJwt” but function order probably will not change. So in order to prevent your tests to fail we can collect these data from controller class like the code below. ...

In a Gatling test, the setUp method is used to specify the scenario that will be run during the test. In the code below, the scenario is specified using the scn variable, which presumably refers to a scenario that has been defined elsewhere in the code. val nbUsers = Integer.getInteger("users", 1000) val myRepeat = java.lang.Long.getLong("repeat", 2) val httpProtocol = http.baseUrl("http://localhost:8080") val scn = scenario("hello").repeat(myRepeat.toInt) { exec(http("GetApplicationInfo") .get("/hello") .check(status.is(200)) .check(jsonPath("$.name"))) } setUp( scn.inject( rampUsers(nbUsers) during (5 seconds) ).protocols(httpProtocol) ) The inject method is used to specify how the users will be introduced into the system under test. In this case, the rampUsers method is used to gradually increase the number of users over a period of 5 seconds. This is known as a ramp-up. The total number of users to be injected is specified by the nbUsers variable. ...

I wanted to test ktor.io with graalvm build, main problem is all code I found using gradle and my project is using mvn here is the code. like other modules I needed to create reflect config json, otherwise ktor serialize is not working properly with graal and when I send a request to “/hello” endpoint I got empty response. I tried to write myself but did not work and at the end I used command below ...

I used Eclipse between 2008-2018. After 2018 I saw everyone was using Intellij I moved too. Then today I was trying to write some aspectj code and created an .aj file. I realized intellij community edition does not really support aj files. I checked vscode it also did not support it, then the old friend eclipse came. It caused some issues because of the old plugin version, but after installation of the new version ajdt plugin it worked. ...
