GetCookies | Assistant for get HTTP ONLY Cookies | HTTP library

The following script mutates the immutable variable jar without errors or warnings. Is this a bug? Or a bug in my understanding?

Please explain why I don't need to use the mutable keyword.

aside: The cookieContainer argument to FSharp.Data.Http.RequestString is not marked as mutable in the definition: https://github.com/fsprojects/FSharp.Data/blob/134a08cda3acb8e746bb25d03692d90ee5caabab/src/Net/Http.fs

I'm trying to scrap data from one famous website and found a question doing this.

This site uses cookies for authentication, and it sets the cookie, then replaces it during the authentication flow.

My problem is that CookieContainer does not replace cookies with the same name, same domain, but in the second case domain starts with dot.

But any browser or Postman does this.

So result of this is double-sent cookie, and the site fails authentication flow.

I have this method which I want to test using mockito

I'm trying to test the getCookieByName method which is used by another method. However, not sure I'm doing this correctly as it seems the method is being called multiple times and it sets the value the first attempt but then is empty on the last call. I think maybe the order for the mock calls may be wrong or some of them may not be needed, but if I remove any of what I still get other errors, so not sure what I'm actually doing wrong.

I'm trying to test a method which calls another method which makes use of a private final static variable initialized inline. I'm then trying to change the value for the variable when the tests run. I've been trying things such as spring reflection or adding a setter for that specific field but maybe I should use something as powermock, which I never used before. I'm on my own trying to implement this with no one to ask so if I could have some guidance on what is the best way to proceed, please.

UPDATE

Based on some feedback I got here, mocking the private final variable may not be what I should do for my my tests. I've opened a different issue here Mock return value for cookie.getValue() using Mockito

I have a CookieFilter class that overrides doFilter method to set a Cookie before my Rest service is invoked:

I've created this, and it's able to get the cookies from Google Chrome when given a specific domain name. However, the values are decrypted. I know there must be a way I can modify my code to decrypt these values.

I am new to Testcafe and implementing a Client Function to read all Cookies by Name that are set by the Website to be tested, as there is no direct way to read all the Cookies in Testcafe and check if a Cookie has a certain name; hence, a Client Function should do the trick. Unfortunately, after checking every possible Ressource on the web, I couldn´t figure out how to call the Client Function with parameters, so that the name of the Cookie to be tested can be passed as Parameter to the Client Function. I didn´t found any example on how to pass Parameters in Testcafe Client Functions.

This is the Client Function:

I am new to Testcafé and need to get all Cookies from a Website, store them in an Object or Array and see, if the name of the Cookie matches against an Array of Strings to see if some Cookies are set; this needs to be done in Typescript; in pure Javascript would be easier, but these are the Requirements.

In order to achieve this, I implemented an Interface with all the Properties that I need from the Cookies:
