kandi X-RAY | tackle-test-generator-cli Summary
TackleTest provides automated test-generation and differential-testing capability for Java unit testing, where unit test cases can be automatically generated on a given application version (the base version) and executed against a modified version to detect differences. The core test generator that the CLI invokes resides in the related tackle-test-generator-core repository. The tool is integrated with two automated unit test-generation tools for Java: Randoop and EvoSuite. So tests can be generated using either of these tools standalone or in combination with CTD modeling, which generates test cases guided by a different coverage criterion that exercises methods based on combinations of different types of method parameters. The goal of CTD-guided test generation is to exercise a method with different combinations of subtypes of the declared types of the method parameters. To do this, the test generator creates a CTD model for each method by identifying possible subtypes of each method parameter type using class-hierarchy analysis and rapid type analysis. From this model, a CTD test plan is generated for a given interaction level; the rows in the test plan become coverage goals for the test generator. This type of test generation puts emphasis on type interactions (or type-based testing), and applying CTD modeling enables the interaction levels to be controlled as well as optimizes the number of coverage goals (and resulting test cases) at an interaction level. tkltest-unit also lets tests to be generated with or without assertions. In the case of EvoSuite and Randoop, the assertions are generated by those tools. In the case of CTD amplification, differential assertions are added by the test generator on states of objects observed during in-memory execution of test sequences. Addition of assertions to tests makes the tests stronger in detecting behavioral differences between two application versions, but it can also result in some false failures when expected differences in program state occur between the versions. If assertions are not added, the only differences detected by the test cases are those that cause the application to fail with runtime exceptions.

QUESTION
While I am testing my API I recently started to get the error below.
...ANSWER
Answered 2022-Mar-29 at 13:29As 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:
Upgrade flask
Pin your werkzeug version
QUESTION
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.
cypress.json
ANSWER
Answered 2022-Feb-16 at 02:33You can try importing the css in the index.ts or index.js file that will be available in the location -> cypress/support/index.ts

QUESTION
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?
ANSWER
Answered 2022-Feb-10 at 13:00Yes. One option (since .NET 6) is to make the tested project's internals visible to the test project for example by adding next property to csproj:

I was watching a conference talk (No need to watch it to understand my question but if you're curious it's from 35m28s to 36m28s). The following test was shown:
...ANSWER
Answered 2022-Feb-08 at 21:40One 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":
- First
Storeexecutes, stores first random value. - Second
Storestarts executing, starts storing second random value. - First
Loadis blocked on the secondStorecompleting due to a lock internal to the database - Second
Loadis blocked on theStorecompleting due to a local internal to the database. - Second
Storefinishes and release the internal lock. - First
Loadcan now execute, it gets second random value. EXPECT_EQfails 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.

How do I resolve this problem. I am just trying to create a test the ensures that that component renders, but for some reason keep getting this problem even though the component is already inside .
I have read other similar questions on here, and the answers all say to put the component inside the , But that doesn't seem to be the issue for me. Please tell me what it is I'm missing?

QUESTION
Would be any difference if I used HTML id attribute instead of data attributes like data-testid?
Reference for the use of data-testid in testing:
ANSWER
Answered 2021-Nov-03 at 10:28On 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.

Install tackle-test-generator-cli
Created an empty configuration file, named tkltest_config.toml, by running the command tkltest-unit config init --file tkltest_config.toml tkltest_config.toml will be created in the working directory.
Assign values to the following configuration options in the configuration file (details on all configuration options are available here): app_name: name of the app under test (this name is used as prefix of file/directories created during test generation) app_build_files: one or more build files for the application. TackleTest will automatically extract the following information from the provided build files: (1) the paths to the application classes, (2) the external dependencies of the application, and (3) the identity of its modules, in case of a multi-module application app_build_type: either maven, gradle or ant
To generate test cases, run the command tkltest-unit --verbose generate ctd-amplified The unit test cases will be generated in a folder named tkltest-output-unit-<app-name>/<app-name>-ctd-amplified-tests/monolith. A CTD coverage report will be created as well in a folder named tkltest-output-unit-<app-name>/<app-name>-tkltest-reports, showing the CTD test plan row coverage achieved by the generated tests.
To execute the generated unit tests on the legacy app, run the command tkltest-unit --verbose --test-directory tkltest-output-unit-<app-name>/<app-name>-ctd-amplified-tests execute JUnit reports and Jacoco code coverage reports will be created in tkltest-output-unit-<app-name>/<app-name>-tkltest-reports.
