Test coverage for test class of trigger is showing 53 constantly - triggers

Question

I am new to salesforce development.I have written test class for following trigger, which is having coverage as 53 only. I tried several times by adding and changing code lines into test class but it is still showing 53. Could you please help me to resolve this?
Thanks in advance. any help would be appreciated.

Hi SAdmin and welcome to the community.
You can use Developer Console in order to check which part of your code is not covered on your test class. Every time you run your test class you are able to see which lines of code is covered by clicking on Code Coverage dropdown on your main apex class.
This way you can see that the lines of code that are covered by tests are blue. Lines of code that aren’t covered are red. Lines of code that don’t require coverage (for example, curly brackets, comments, and System.debug calls) are left white.
Please check this guide out to find some more info.
