kandi X-RAY | afl-cov Summary

afl-cov is a Python library typically used in Testing applications. afl-cov has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. However afl-cov build file is not available. You can download it from GitHub.

afl-cov uses test case files produced by the AFL fuzzer afl-fuzz to generate gcov code coverage results for a targeted binary. Code coverage is interpreted from one case to the next by afl-cov in order to determine which new functions and lines are hit by AFL with each new test case. Further, afl-cov allows for specific lines or functions to be searched for within coverage results, and when a match is found the corresponding test case file is displayed. This allows the user to discover which AFL test case is the first to exercise a particular function. In addition, afl-cov produces a "zero coverage" report of functions and lines that were never executed during any AFL fuzzing run. Although of no use to AFL itself, the main application of afl-cov is to wrap some automation around gcov together with AFL test cases and thereby provide data on how to maximize code coverage with AFL fuzzing runs. Manual interpretation of cumulative gcov results from AFL test cases is usually still required, but the "fiddly" steps of iterating over all test cases and generating code coverage reports (along with the "zero coverage" report) is automated by afl-cov. Producing code coverage data for AFL test cases is an important step to try and maximize code coverage, and thereby help to maximize the effectiveness of AFL. For example, some binaries have code that is reachable only after a complicated (or even cryptographic) test is passed, and AFL may not be able to exercise this code without taking special measures. These measures commonly include patching the project code to bypass such tests. (For example, there is a patch to solve this problem for a CRC test in libpng included in the AFL sources at experimental/libpng_no_checksum/libpng-nocrc.patch.) When a project implements a patch to assist AFL in reaching code that would otherwise be inaccessible, a natural question to ask is whether the patch is effective. Code coverage results can help to verify this.

            As of version 2.1.0, werkzeug has removed the as_tuple argument to Client. Since Flask wraps werkzeug and you're using a version that still passes this argument, it will fail. See the exact change on the GitHub PR here.

            You can take one of two paths to solve this:

            1. Upgrade flask

            2. Pin your werkzeug version

            Cypress component testing is not loading CSS while running testcases
            Asked 2022-Mar-29 at 20:26

            We are building web components using stencil. We compile the stencil components and create respective "React component" and import them into our projects.

            While doing so we are able to view the component as expected when we launch the react app. However when we mount the component and execute test cases using cypress we observe that the CSS for these pre built components are not getting loaded.

            Is there a way to unit test top-level statements in C#?
            Asked 2022-Feb-10 at 13:00

            I was fiddling with top-level statements as the entry point for a simple console app, since the new .NET 6 template use them as a default.

            Yet, as the language specification very clearly states:

            Note that the names "Program" and "Main" are used only for illustrations purposes, actual names used by compiler are implementation dependent and neither the type, nor the method can be referenced by name from source code.

            So, if I can't reference the implicit Program class and it's Main() method, would it be possible to write unit tests to check the execution flow of the top-level statements themselves? If so, how?

            One of the speakers said: "you can only expect that storing data to a production service works if only one copy of that test is running at a time."

            Right. Imagine if two instances of this code are running. If both Store operations execute before either Load operation takes place, the one whose Store executed first will load the wrong value.

            Consider this pattern where the two instances are called "first" and "second":

            1. First Store executes, stores first random value.
            2. Second Store starts executing, starts storing second random value.
            3. First Load is blocked on the second Store completing due to a lock internal to the database
            4. Second Load is blocked on the Store completing due to a local internal to the database.
            5. Second Store finishes and release the internal lock.
            6. First Load can now execute, it gets second random value.
            7. EXPECT_EQ fails as the first and second random values are different.

            The other speaker said: "Once you add continuous integration in the mix, the test starts failing".

            If a CI system is testing multiple instances of the code at the same time, race conditions like the example above can occur and cause tests to fail as the multiple instances race with each other.

            The SignUpView is missing a routing context in your test. Import a memory router and wrap the component under test so it has a provided routing context.

            On the surface, I don't see any technical difference.

            But in terms of readability, data-testid may notice other developers that this is used for test case specifically, while id is may be in terms of styling.

            Also id or class selectors can be changed more often if implementation changes.
