  1. Thanks for your personal marvelous posting! I genuinely enjoyed reading it, you can be a great author.I will make certain to bookmark your blog and definitely will come back in the future. I want to encourage yourself to continue your great posts, have a nice weekend!

  2. Undeniably believe that which you said. Your favorite justification seemed to be on the web the easiest thing to be aware of. I say to you, I definitely get annoyed while people think about worries that they just do not know about. You managed to hit the nail upon the top and also defined out the whole thing without having side-effects , people can take a signal. Will likely be back to get more. Thanks

    You mention that TestComplete can do load testing, but wouldn’t you need LoadComplete for that?

    This is really great…been looking for this and it really help me on my decision on TC…

    Thank you!

    It looks latest SilkTest supports SilverLight (
    And TestComplete for sure is only Windows family, no Linux.
    SmartBear is not extending TestComplete’s LoadTesting, and you should use separate product for this – LoadComplete. Read Sergei’s Sokolov post at So LoadTesting should not be compared.

    TestComplete doesnt support Linux platform…

  7. Maria says:

    Seems like this person is pro Testcomplete because I just finished a comparison and I notice a lot of the comments are simply not true. Linux, Loadtesting, Silverlight etc

  8. alexander says:

    TestComplete never supported C# or C++.
    You must edit the article since it’s a total lie.
