Introduction:
I'm new to Jmeter, so I'm working with basic tasks but I have a mentor. We are working with distributed architecture, one master and one slave in my local network executing a real world working testplan.

Problem:
No response from slave:
We have installed and configured Jmeter 5.3 and java version "1.8.0_271" in both slave and master with windows 10 machines. Each machine can ping the other. When the testplan is executed in the master, from the JMeter GUI or CLI, the slave recognize the order and start the proccess, it also notify the end, but there is no response in the .jtl file another than the file header. We have tryed with RMI enabled and disabled. The logs dont show errors.

System specs: OS W10, Jmeter 5.3, Java 1.8, Jmeter plugin: jmeter-plugins-manager-1.4.jar (Plugins installed: Custom Thread Groups, 3 Basic Graphs, Console Status Logger), Windows Firewall is disabled in both machines, Jmeter properties (Master remote_hosts: Slave ip, Slave remote_hosts: 127.0.0.1)

JMeter GUI execution log (Master):

Question:
So the question is basically what can be wrong to make the server recognize the start calls, send the end signal, but don't write the .jtl file.

Not really, as per JMeter project main page:

JMeter is not a browser, it works at protocol level. As far as web-services and remote services are concerned, JMeter looks like a browser (or rather, multiple browsers); however JMeter does not perform all the actions supported by browsers. In particular, JMeter does not execute the Javascript found in HTML pages. Nor does it render the HTML pages as a browser does (it's possible to view the response as HTML etc., but the timings are not included in any samples, and only one sample in one thread is ever displayed at a time).

The only way to measure browser rendering time is using a real browser, if you want to do this along with the existing JMeter performance tests - go for WebDriver Sampler, it provides JMeter integration with Selenium browser automation framework so you will be able to kick off a real browser and measure its rendering time (response time of the WebDriver Sampler will be the time from opening the page till the rendering finishes.

If you need the breakdown - consider using Navigation Timing API

The purpose of the unit tests and GUI automated tests are different. The unit tests (usually implement by developers) should verify vary input and output of one function that under the test. It may be implemented with help the mock system if required. The unit tests usually run fast and all such suite haven't take more than 1 sec. The GUI test are simulated the user behaviour (we often call them end to end tests) and may take much more time for the execution.

1. I wouldn't recommend write the unit tests with help of GUI automation because you want run them fast, rerun every time , be very stable and not be affected from other objects like browsers.
2. It is much easy to write the automated tests using some automation recording however usually it is much less stable than code that you will write by yourself using the appropriated API.
3. I am not sure that I follow you here but again the unit tests preferable write in code w/o GUI, the system test usually should be written with help GUI automation environment like Selenium.

Catch2 tries to colorize the console and mistakenly thinks TestToolbar is a color-coded console. But you can help him - just add the parameter

--use-color no

If the parameter is difficult to write (I know CLion can be a little strange), then you can write CATCH_CONFIG_COLOR_NONE directly in tests

I test Xamarin mobile applications for Android and iOS, tests are carried out both on real devices and on emulators.
However, recently it became necessary to distinguish between a test run on an emulator and on a physical device.

Question: Is there a way in the process of testing .apk or .ipa to understand where the application is running - on an emulator or on a real device?
Are there any system parameters that always differ from the real device on the emulator?
