    java selenium-webdriver selenium-chromedriver
    I am trying to execute my selenium test scripts using chrome driver 2.6 (chrome browser v.29). Test cases are smoothly executed. But, some of my test cases fails because it gives unexpected alert exception. Same scripts are running successfully in firefox (have ignored unexpected alerts in firefox profile).My question is – Is there any provision of ignoring unexpected alerts in chrome profile? If no, how to handle it?Any help will be highly appreciated.Thanks in advance.

    Is it possible for selenium to wait for an user input if an unexpected event occurs in the script(like a message box/ new window/ warning / alert or any other interruption)? For example if some new functionality is added to the code and when selenium script is run, the test shouldn’t break but should wait for manual intervention where the condition in the new functionality occurs.

    Currently I am noticing my automated tests (CodedUI) are running a bit slow at times. I want to run a performance profiling tool on them as they run through VS2010. I have tried to use Red Gate’s ANTs Profiler but am confused as to what process (or other?) I am supposed to attach it to.The closest I came was by starting the Profiler from commandline and having a Mstest.exe call that runs a few tests as the process argument. This only returns me VS method performance and not my own test code.//e.

    java logging junit jmeter
    I’ve noticed that when I run a Junit sampler with Jmeter, the messaging is pretty bare. If an exception occurs, Jmeter will report it, but everything else that happens in my tests has to get outputted using Log4J or another logging tool. Is there a way just to log result back to Jmeter? Do they have an API for this?

    In our VB6 applications, we added a few utility functions for tracking the amount of time spent in a function. We did this to track performance bottlenecks.Basically, how it worked was there were two utility functions: StartTickCount() and EndTickCount(). You would pass the name of the function in each, and the functions would use a dictionary to get the tick count when StartTickCount() was called, and then subtract the tick count when EndTickCount() was called. This wasn’t perfect because it

However, I cannot get consistent results. My methodology involves repeating both methodologies 10,000 times and measuring the results with the Measure-Command cmdlet.
