robotframework - How Do I return to main page only when one of test within test suite failed?

Question

I have written test suite

test cases as follows:

when one of test case failed, I want the screen back to main page. so next test case can start correctly.

how can I do so? e.g. While executing current test, if previous case failed, then go to main page before start current test. otherwise, proceed current test as usual.

Every test should be independent and not rely on side effects from previous tests. That means that the test setup of each test should be responsible for making sure the home page is the current page.

For example, you can make a keyword named Go to main page, and call that as part of your test setup. That keyword can check the current page, and if it's not the current page then do whatever is necessary to get back to the main page.
