I have tried the example you provided and it works fine. However, I am still having trouble getting it to work in my code. I am using the code in a python script, and I am not sure how to import the code you provided. I have tried using the following:11from kconfiglib import *12import subprocess13import sys14def main():15 kconf = kconfiglib.NewKconfig("Kconfig")16 expr, err = kconf.ParseExprAnd("CONFIG_FOO && CONFIG_BAR")17 raise Exception(err)18 print(expr.Eval(kconf))19 sys.exit(main())20Traceback (most recent call last):21 sys.exit(main())22 kconf = kconfiglib.NewKconfig("Kconfig")23import subprocess24import sys25def main():

Rebuild Confidence in Your Test Automation

These days, development teams depend heavily on feedback from automated tests to evaluate the quality of the system they are working on.

Your Favorite Dev Browser Has Evolved! The All New LT Browser 2.0

We launched LT Browser in 2020, and we were overwhelmed by the response as it was awarded as the #5 product of the day on the ProductHunt platform. Today, after 74,585 downloads and 7,000 total test runs with an average of 100 test runs each day, the LT Browser has continued to help developers build responsive web designs in a jiffy.

Test Optimization for Continuous Integration

“Test frequently and early.” If you’ve been following my testing agenda, you’re probably sick of hearing me repeat that. However, it is making sense that if your tests detect an issue soon after it occurs, it will be easier to resolve. This is one of the guiding concepts that makes continuous integration such an effective method. I’ve encountered several teams who have a lot of automated tests but don’t use them as part of a continuous integration approach. There are frequently various reasons why the team believes these tests cannot be used with continuous integration. Perhaps the tests take too long to run, or they are not dependable enough to provide correct results on their own, necessitating human interpretation.

How To Write End-To-End Tests Using Cypress App Actions

When I started writing tests with Cypress, I was always going to use the user interface to interact and change the application’s state when running tests.

How To Use driver.FindElement And driver.FindElements In Selenium C#

One of the essential parts when performing automated UI testing, whether using Selenium or another framework, is identifying the correct web elements the tests will interact with. However, if the web elements are not located correctly, you might get NoSuchElementException in Selenium. This would cause a false negative result because we won’t get to the actual functionality check. Instead, our test will fail simply because it failed to interact with the correct element.
