kandi X-RAY | redqueen Summary
Redqueen is a fast general purpose fuzzer for x86 binary applications. It can automatically overcome checksums and magic bytes without falling back to complex and fragile program analysis techniques, such as symbolic execution. It works by observing the arguments to function calls and compare instructions via virtual machine introspection. Observed values are used to provide inputs specific mutations. More details can be found in the paper. This fuzzer is built upon kAFL and requires support for Intel VT-x as well as Intel Processor Trace. The Paper, Talk and Slides describing Redqueen were published at NDSS 2019.

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:
QUESTION
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
Store
executes, stores first random value. - Second
Store
starts executing, starts storing second random value. - First
Load
is blocked on the secondStore
completing due to a lock internal to the database - Second
Load
is blocked on theStore
completing due to a local internal to the database. - Second
Store
finishes and release the internal lock. - First
Load
can now execute, it gets second random value. 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.
QUESTION
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?
** My app.tsx**

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.

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.
