In image-based tests, you may encounter the following problem:
Long Search for Controls
To simulate an action on an item in image-based tests, TestComplete finds it on the screen. TestComplete searches for the image on the screen pixel-by-pixel. This can take a lot of time, especially if you set high pixel or color tolerance values.
To avoid the issue, use lower pixel and color tolerance values. This will increase the test run speed.
To learn how to edit the pixel tolerance and color tolerance values, see Image Set Item Properties and Setting Recognition Parameters for Multiple Items at Once.
To learn about other factors that can affect image comparison in TestComplete, see Factors Affecting Image Comparison.
