But I’m using HttpFilters that the reason CrossOrigin is blocked it showing when I hit in angular

Srikanth_patel 2022-06-27 18:16:44

Postman it’s working fine

Srikanth_patel 2022-06-27 18:17:10

You forget to allow option method here

Writing test-cases is more about conceptual understanding of the requirement and your code, than about learning the test frameworks – just like how programming is more about problem solving abilities.

A program written can fail during compile-time or run-time & due to various reasons – ranging from typo error to incorrect usage of language features. We can clear the compile-time errors ourselves as we can encounter it while programming. We might miss to predict the run-time errors though. The test-cases are exactly to fill that gap.

A well-written test-case should make sure that the output at each stage is correct. Testing can be done on various levels like Unit testing, Integration testing, Interface testing, Security testing, etc.

Example test-cases would be to test whether the input/output data-types are correct (unit test), whether the code connects with db properly & whether the data is getting updated in the tables (integration test), etc. How we write them will depend on which framework is used. There are many frameworks like JUnit, Selenium, Mockito, etc.

OK understood
Thanks

Here you have to specify options methods also

HttpFilters also I added allowed methods

shiv 2022-06-27 18:19:16

Get method should be there and option method also be there
