Testcase is something which we dont write in Navision, it's a file or a word document or a visio document which acts as a evidence of the testing we did.

The test assignment is the best opportunity to introduce yourself. Unlike the interview and the practical task, the test task is performed without the presence of strangers, not in someone else's office, without a stressful environment and often without time limits. Here they helped me with a test task https://pro-papers.com/case-study-writing , all the same professional writers.
