Mockito VS anyhow

Mockito 5 Released (1 min)🎉 https://github.com/mockito/mockito/releases/tag/v5.0.0

For those using a "release" testBuildType for integration tests, what does your mocking setup look like? My app is stuck on Mockito 2.23.4, because higher (> 1.8.12) versions of Byte Buddy required beyond that point [do not play nicely with non-debuggable APKs](https://github.com/mockito/mockito/issues/2302). Solutions I've considered so far:

Mockito

The code is pretty self explanatory but here's a quick run down. o.getClass().getDeclaredFields() gets us an array of all the fields. We then have a enhanced for loop that loops over the array. Check if the field is annotated field.isAnnotationPresent(Gucci.class). If it is then we set its modifier to true with field.setAccessible(true);. If we don't do this and the field is private we will get an error. Then we get the binary name of the field, field.getGenericType().getTypeName();, remember its just the package and the class name. Lastly we set the value of the field, field.set(o,dynamicInjection(classLoader,binaryName). With that we have now created a dependency injection annotation with the Junit 5 extension model. Now I am sure you can see the tower of exceptions, which is obviously not ideal. I'm not sure how I want to handle all the exceptions yet. However, I will be digging around the Mockito code base to see if I can find how they handle all their exceptions.

Mockito 3.11.* releases

Hi, I've been trying to write parquet files on android for the past couple of days, and have really been struggling to find a solution. My original hypothesis was to just use the java parquet implementation (https://github.com/apache/parquet-mr), but I've since realized that not all java libraries play well with Android. I've gone through essentially dependency hell trying to franken-fit the library into my project, and imported as much as i could before hitting walls such as this one (https://github.com/mockito/mockito/issues/841).

Depending on your use case, thiserror and/or anyhow.

There is ? as well as the anyhow(https://github.com/dtolnay/anyhow) crate that deals with long nested result chains.

There are crates out there that help you reduce this boiler plate. thiserror is good for creating custom errors and color-eyre or anyhow are good for dynamic errors.

Give anyhow a look.

I've brought anyhow::Result into scope, making error handling super easy to use. We don't need to specify all our Error types. It can automatically convert any errors that implement std::error::Error, which should be all of them. If an error propagates all the way up to main(), we'll get all the info it's captured printed to stdout.

Alternatively, if you've got a lot of error types and you're outside a library (so directly in a binary where you don't plan to reuse code elsewhere) you can use anyhow. This gives you an error type you can basically propagate any other error through. On top of that you can attach context information at every return. It's basically a more complicated Result>.

One approach is to define a separate error type for each crate and then use anyhow, eyre or Box to wrap the error, whever a function can return errors originating in several different crates.

Have you tried anyhow and thiserror for making it as simple as .context("Message") or ? to type-convert and propagate errors up the call stack?
