Unit testing

How to ensure high quality components.

We recommend adding unit tests to all of your components in a project as soon as possible. Implementing unit tests not only ensures that your component works, but it also makes the project more maintainable in the long run as you will be notified when a component breaks.

This page describes how to add a unit test to your component.

Create unit test

Below is an example of how to add a unit test to a Viash component.

#!/bin/bash

## VIASH START
meta_executable="target/example_bash"
## VIASH END

echo ">>> Create input test file"
echo "foo" > foo.txt

echo ">>> Run executable"
$meta_executable --input foo.txt --output bar.txt

echo ">>> Check whether output file exists"
[[ -f bar.txt ]] (echo "Output file could not be found!" && exit 1)

echo ">>> Check whether input and output file are the same"
cmp foo.txt bar.tx (echo "Input and output files are different!" && exit 1)

echo ">>> Test finished successfully"

string content = "hello\nthere\n";

Console.WriteLine(">>> Create input test file");
File.WriteAllText(inputPath, content);

Console.WriteLine(">>> Run executable");

  1. Create an input file “foo.txt” with some sample content.
  2. Run an executable file specified in the “meta” dictionary with the arguments “–input foo.txt” and “–output bar.txt”.
  3. Check whether the output file “bar.txt” exists.
  4. Check whether the content of the output file is the same as the content of the input file.
  5. If both checks pass, the script prints “Test finished successfully”.
Important

A test script doesn’t need to be written in the same scripting language as the main script, as long as all of the required dependencies are available. This means the main script could be written in R, but the unit test could be written in Bash.

Add test to config

Next, we need to add the unit test to the test_resources section in the Viash config.

Note that if you can add multiple unit tests to the test_resources section, they will all be evaluated. You can also add other resources, similar to what is described in the page on adding resources.

Run the unit test

You can run the unit test as follows:

Cleaning up temporary directory

When running viash test, Viash will follow the following steps:

  1. Create a temporary directory
  2. Build the component into the main executable
  3. (Re-)build the Docker image for the component
  4. Iterate over all unit test scripts:
  1. Build the unit test into an executable
  2. Run the unit test, passing the main executable as an argument
  1. Return exit code 0 if all of the above steps succeed, otherwise 0

Bonus: unit testing all of the components

If you have multiple Viash components located in a directory called src/, what happens when you run the following?

viash ns test --parallel --src src/
