Hey Hari, thanks for interest in ZAPTEST.
1.About your first observation. The delay that you have during script execution is more likely caused by “exist” method, as it having exactly 45 seconds default timeout. Usually this mean your test step is “failed” if this delay expired. Does it looks close to what you have in your script?
Though we have delay parameter for steps execution in ZAPTEST app. Navigate to TOOLS -> Options -> Runtime -> Global Delay (in ms).
2. Did you mean that code highlighting not working on some of your lab machines? Actually it is default parameter and can’t be changed (turned off), however it may be some graphical inconvenience on your environment. We will appreciate if you provide more details.
