Top 23 Go Testing Projects

Go through Learn Go With Tests to learn how to test the code correctly in Go.

Gor
GoReplay is an open-source tool for capturing and replaying live HTTP traffic into a test environment in order to continuously test your system with real data. It can be used to increase confidence in code deployments, configuration changes and infrastructure changes.
Not OP, but that is the idea. I use this tool for it, as it is dead-simple to get running and fairly configurable: https://github.com/buger/goreplay
-
Scout APM
Scout APM - Leading-edge performance monitoring starting at $39/month. Scout APM uses tracing logic that ties bottlenecks to source code so you know the exact line of code causing performance issues and can get back to building a great product faster.
-
At a high level, mocking the client means creating a new struct that implements the interface you are testing (mocking the interface). Then, provide your mocking client to the code under test. A good library with examples is testify.
-
For a generic usecase, do you see Go-convey adding any benefit over simple golang t.Run?

The first day, I wrote my tests for some GET routes. We use something called go-mock in our unit tests, which allows you to only focus on testing the function you're writing. Because of this, I found that you still needed to have a good idea of the code you want to write while writing out the tests. In our case, we needed to mock out our calls to an external API. If you asked for my opinion after the first day, I would've told you that I could envision the benefits of TDD for something like end to end testing, where it's a black box and you're only verifying that the output is what's expected from a given input. But for unit testing, it wasn't any different than just writing the code first.

toxiproxy
:alarm_clock: :fire: A TCP proxy to simulate network and system conditions for chaos and resiliency testing (by Shopify)
Note that we are creating a custom docker network and a Toxiproxy container. For the initial tests this is not required, but we need it later on when we want to simulate network failures. For the sake of simplicity we will only use a single etcd node. In a production scenario you should have an etcd cluster of at least three nodes.

Nanos
Run Linux Software Faster and Safer than Linux with Unikernels.
-
terratest
Terratest is a Go library that makes it easier to write automated tests for your infrastructure code.
Terratest is probably the closest one can get now a days to testing the specific peace of terraform code. It is a Go library, and requires one to write tests in Go. This is obviously a potential limitation as not all teams have knowledge in Go. On the upside, I would argue that the learning curve of learning Go to get the basics - read enough for writing terraform tests - is not steep if you know already at least one programming language.
-
The BDD testing framework Ginko [1] has some "weird" / unidiomatic patterns, yet it is very popular
-
The repository is private but there is a CI/CD no-downtime deployment process. So fancy! I use goss to test the built image along with the docker/build-push-action. The end of my ci.yml GitHub Action workflow looks like this:

> it shows the limitations of the language that you can't just build this inside the language.
Not sure why you'd make that assumption. https://github.com/dvyukov/go-fuzz
-
realize
Realize is the #1 Golang Task Runner which enhance your workflow by automating the most common tasks and using the best performing Golang live reloading.
-
Example auth middleware: https://github.com/grpc-ecosystem/go-grpc-middleware/blob/master/auth/examples_test.go
-
Project mention: Go Package for better integration tests: github.com/ory/dockertest | dev.to | 2021-04-23
We have different ways to write our tests depending on what datastore we are using, for example if we are testing database calls that happen to be using database/sql then importing a package like github.com/DATA-DOG/go-sqlmock could work.

Gauge is a Behavior Driven Java testing framework launched by ThoughtWorks.Inc. This is also one of the best Java Testing Frameworks, which allows software engineers to develop automated frameworks and speed up the software development procedure.
-
One thing to keep in mind about reflect.DeepEqual is because of the way it is implemented you could get positive results when the values are not actually the same, see this comment for reference.
-
selenoid
Selenium Hub successor running browsers within containers. Scalable, immutable, self hosted Selenium-Grid on any platform with single binary.
-
conftest
Write tests against structured configuration data using the Open Policy Agent Rego query language

Future plans I have is for these workers to actually run chromedp (https://github.com/chromedp/chromedp) or something similar to generate a har file. Currently the har file can't be generated with chromedp but you could use a proxy like martian (https://github.com/google/martian) maybe to generate this. Then you could results like https://tools.pingdom.com/ (the tool seems not to show each file request for me anymore) for every uptime check and keep stats for this. You are not only testing the uptime then but also the full load time of the page along with checking for other potential problems.
