what tool will be used for test coordination procedures in the Acceptance testing of Diag. Can any body explain a bit about Test Coordination Procedures in Acceptance Testing of Diag.
Thanks in Advance
can any body help me creating the skeleton of the Acceptance Testing

I am starting to write tests for database calls and queries. But I was wondering, since it doesn't depend on any other function, then writing test for database calls are unit tests?
Edit: This is around a Node.js environment
The database is separate to the application that you are testing, and as such, the tests would be integration tests rather than unit tests.
Note that unit tests are limited to dealing with single pieces of software in isolation. If you explicitly want to unit test your code as it stands (without making actual database calls), you can make use of a mocking framework, such as Moq.
For instance, I assume this is what SDETs do?
They don't actually write the functional code but they're able to write integration/unit tests, am i correct?
But can someone learn to read code and then start writing tests?
This is actually a good question. I have been at the same place when I was working only on Manual Testing. Here is how I experienced things when I transitioned to automation. To answer your question, yes someone can read code and start writing tests on it but you need to understand the code that you are going to test.
There are different types of testing methodologies that are used when testing an application. These tests are done in layers so that the application is properly tested. Here is how the layering looks like:
1) Unit testing: This part is usually written by developers. This is because they have written the code and know the functionalities of the code and is easier for them to write. I am an SDET and I have written unit tests. There was only one opportunity that presented itself and it was when we were refactoring our code and there was a lot of room to write Unit Tests. In unit tests, you test functions in isolation by giving it some values and verifying an expected value. This is not something an SDET does, but should be able to do if provided the chance.
2) Integration testing: This part is also usually written by developers but the definition of integration testing is a bit vague. It means testing multiple modules in isolation. This can be modules in backend or modules in frontend but not together. Frameworks that help achieve this are code level integration tests for the technology you are using. Like for Angular application, there are deep integration tests that test the HTML and CSS of a component and there are shallow integration tests that just test two component's logic together. This can be written by an SDET but is usually written by the developer.
3) API testing (contract based testing): Pact helps us achieve this. There are other tools like rest assured, postman and jmeter that help in testing API end points. Pact helps test the integration of APIs on the frontend and verifies that integration in backend. This is very popular with microservices. This is something that can be written either by the developer or by the SDET.
4) End to End testing: This is something that is the sole responsibility of SDET. This covers testing of user flows depending on user stories. It is testing the entire stack together. Backend and frontend. This allows SDETs to automate how a user would use the application. This is also called as blackbox testing. There are different frameworks that help achieve this. Selenium, Protractor, Cypress, Detox etc. This is the sole responsibility of an SDET.
5) Load testing: This is again something that an SDET does. Using tools like hey, jmeter, loadrunner etc. These tests allow the SDET to initiate a heavy load on the system and check for breaking points of the system.
6) Performance testing: Testing the performance of the webpage for an end user depending on the page load time, the SEO optimisation and the weight of elements of page. This is something achieved by google's lighthouse tool that is an amazing tool to use. I am not aware of anything else that is as amazing as lighthouse because it gives us a lot of data that we can use to improve our website. This is a primary job of an SDET.
7) CI/CD: Continuous Integration and Continuous Deployments is something that requires architectural knowledge of the system. This is something you can do when you are an SDET3 or a lead QA engineer. For systems like AWS and GCP, using CI build tools like Jenkins and CircleCI, one can set up a pipeline that runs all the above tests when ever a branch is merged into master or whenever a pull request is created. Creating the pipeline will require you to have knowledge of Docker, Kubernetes, Jenkins and your test frameworks. First you dockerize your tests, then you build the image and push it to a directory in cloud, then you use the image to create a kubernetes job that runs everytime a change is presented in your code.
These are the levels of work that an SDET does. It takes time and hard work to have an understanding of all testing frameworks and how everything fits together. An SDET should have knowledge of the server, http protocols, frontend, backend, browsers, caching, pipeline management and orchestration of tests.
Yes, sure. You can write unit tests increasing test coverage of the codebase. That's very qualified work from software test engineering since you need to be aware what is going on in the code. This skill is definitely great!
I advise you to take a look on so called "mutation coverage". Usage of mutation coverage as a better metric than simple unit test coverage. Mutation tests are changing logical operators in the different parts of the codebase (making so called "mutants") and then are running unit tests to find out how many unit tests will fail showing their effectiveness (if after mutants were injected the result is the same as without them - unit tests quality is low and they won't catch any new injected issues to the codebase).
How can i do smoke and monkey testing in ABAP? Are there tools for that ?
Smoke testing can be automatized by using eCATT. Note that the creation of eCATT tests is quite time-consuming, so you should do a cost-benefit analysis beforehand.
I don't know of any tools for monkey testing, except maybe creating a ABAP Unit test suit which uses randomly generated data.
I know it is possible to separate Integration and Unit test code coverage in Sonar, but is it possible to retrieve separate pass/fail results for Integration and Unit tests? Thanks
No, unfortunately, this is currently not possible.
Feel free to start a discussion on this topic on Sonar user mailing-list.
software product is integrated and complete ,now to check whether it meets the intended specifications and functional requirements specified in requirements documentation:-
integration testing or functional testing or user acceptance testing
Yes this is a discussion in many projects. What is the scope of the different test phase and I think you ask a very valid question I have discussed very often in projects.
The answer is opinion because I have read different answers in different books and standards and it also depends on the size of the software and the kind of the software.
Here are good answers
In my world normally integration testing is to see whether it works with all up-stream and down-stream systems while functional testing is done on a system alone. But often the functional testing is an end-to-end test and cannot be done standalone so the integration and functional testing becomes the same test phase.
user acceptance testing usually is done by someone else and is the client who gives his sign-off and does his own set of test cases.
