Ces 4 1 Test Reviewer Free Download Pdf
Pablo Barjavel
Where I work, we have very few rules about what constitutes a code review. In addition to going through the code, I tend to briefly test out the software I'm reviewing (in my case, it's always our website) just to see if there are any glaring errors, at least if the project is large It has been the case where a code reviewer here has given anywhere from none to many suggestions in their feedback, but in fact the site did not load at all or simply did not function as it was supposed to.
Finally there are some very obvious errors that can come up from even brief testing that may not be obvious at all from looking at the code (or perhaps I'm just an inferior reviewer). Moreover, I think that some developers and testers may have a very different mindset in terms of how they use software, so a reviewer may find issues that a tester would not (and certainly vice versa).
I believe that code review is a very important step in the development process for catching errors in maintainability, semantics, consistency, standards, and even syntax. The questions I put forth are: should code reviewers actually test the software? If so, is it their responsibility or should this practice be controlled as part of the development process? If they are to test, how much testing is reasonable? If they find errors in their testing, how much time (if any) should they spend looking at the code to find the error vs. simply providing reproduction steps for the developer to debug on their own?
I covered a lot of your question in my answer trust-factor-in-code-review. I would expect code being review to have been tested by the developer. Further testing should be covered in the various test suites. I'll expand on testing a little as that is your specific question.
I would answer "No, testing is not part of the code review process". However, there are classes of errors that are easier to spot in code reviews than in testing. There are also coding techniques which are more prone to error which can be identified in code reviews. For example a code review can identify poor variable naming which is difficult to automate.
For any non-trivial code, you will not be able to cover the full set of functionality in a reasonable amount of time. However, the unit tests should ensure that the code is functional and fails when expected.
Watch for code that implements functionality available in libraries. In addtion to its test cases, library code gets heavily tested though use, and may have important optimizations and safety checks. Either way, your programmer's implementation won't get fixed when the library does. If library functionality needs to be extended, use a wrapper (developed once for the project or organization). Use as much "Not invented here" technology as possible.
In my opinion it depends on how much test coverage the code changes have, and what sort of testing your QA team is performing. During review, you can see in the code the various inputs that are handled. If tests correctly cover all of these inputs, then I would think it'd be a waste of time for the code reviewer to manually test these. However, if some (or all) of these inputs are not covered by tests, it would be prudent for the code reviewer to test these inputs, as the QA team, who presumably does not have access to the source, will not necessarily hit these cases in their testing.
By the time the code gets to a code review, the developer should have written unit tests, successfully built both the code under review and the unit tests, and have all currently-written unit tests passing. Because of this, the code reviewer should not have to test the code - the author of the code should have already done it. If a developer submits code for a code review that does not execute, compile, or pass tests, they should be held accountable for wasting the time of everyone involved in the code review.
That said, it might be a good idea to also review the unit tests that correspond to the code under review to ensure that all the essential cases are covered, there are no extraneous test cases that would slow down test execution, and perhaps point out some other cases that should be covered if there's sufficient time and/or resources. Improving test quality can only improve the overall quality of the project.
More and more systematic reviews of diagnostic test accuracy studies are being published, but they can be methodologically challenging. In this paper, the authors present some of the recent developments in the methodology for conducting systematic reviews of diagnostic test accuracy studies. Restrictive electronic search filters are discouraged, as is the use of summary quality scores. Methods for meta-analysis should take into account the paired nature of the estimates and their dependence on threshold. Authors of these reviews are advised to use the hierarchical summary receiver-operating characteristic or the bivariate model for the data analysis. Challenges that remain are the poor reporting of original diagnostic test accuracy studies and difficulties with the interpretation of the results of diagnostic test accuracy research.
