The REDcap Cypress Test Framework enables automated feature testing for REDCap.
This repository serves as a starting point for running and writing your own automated feature and regression tests, which can be used to validate the features and functionality of your REDCap environment.
Features are written using the Gherkin domain-specific language.
Core REDCap features, written in Gherkin, are posted to a repository guided by the Regulatory & Software Validation committee: https://github.com/aldefouw/redcap_rsvc
If you are a developer, please start by visiting the REDCap Cypress Developer Toolkit, located here: https://github.com/aldefouw/redcap_cypress_docker
The Developer Toolkit is the best way to get Cypress up and running on your developer machine.
Cypress will understand your environment only if you describe it accurately.
Your description will live inside an environment variable definition file.
You will need to set the variables appropriately in cypress.env.json in order for your test suite to function.
To get you started, an example file named cypress.env.json.example is included within this repository.
Here is an example environment variable setup:
{
"users": {
"admin": {
"user": "admin_user",
"pass": "Testing123"
},
"standard": {
"user": "test_user",
"pass": "Testing123"
}
},
"redcap_version": "13.1.7",
"redcap_source_path": "../redcap-source",
"mysql": {
"host": "docker exec -i redcap_docker-app-1 mysql",
"path": "mysql",
"port": "3306",
"db_name": "redcap",
"db_user": "root",
"db_pass": "root"
}
}
Below are descriptions of the configuration variables shown above.
The version of REDCap that you are testing against. This is a critical value to set so that Cypress knows the correct URLs to use when testing. Note that the version of REDCap you specify here MUST be available on your machine in order for tests to work.
The JSON array that contains several keys, which are critical for your database structure and seeds to be populated correctly before each and every test spec.
The hostname or IP address of your MySQL database host.
For many of us, this will likely be either localhost, 127.0.0.1, or a reference to a Docker container via db. Keep in mind that there are subtle nuances between localhost and 127.0.0.1. Thus, you need to choose the option best-suited to your environment.
The path to your mysql binary.
For many of us, this will probably be mysql, but you could also use a full path like /usr/local/opt/[email protected]/bin/mysql if necessary. If you are on a Unix-like environment, you can often determine your full path by entering which mysql at the terminal window. You can also reference a binary within a Docker container like this docker exec -i redcap_docker-app-1 mysql
The port to your MySQL instance.
This is usually 3306 on standard setups, but for many of us running Docker instances we may wish to use an alternative port so we can differentiate between the standard MySQL instance that is installed on a local operating system and the Docker instance itself.
The name of your MySQL REDCap database.
This is typically redcap but not always. You'll want to check your database.php file on your test instance of your REDCap installation to determine this value.
The username of your MySQL REDCap database user.
This is typically root on local instances of MySQL or local Docker containers. You'll want to check your database.php file on your test instance of your REDCap installation to determine this value.
The password of your MySQL REDCap database user.
This is typically root on local instances of MySQL or local Docker containers. You'll want to check your database.php file on your test instance of your REDCap installation to determine this value.
To create non-deterministic tests, the REDCap Cypress Test Framework resets the database to a known state before each feature is run.
Before the test suite is run, the appropriate tables for your specified REDCap version are installed into your MySQL database. To achieve this, the framework needs to know about where your REDCap source code is located.
You will need the following environment variables configured in your cypress.env.json file:
-
"redcap_source_path": "../path/to/redcap/source/here": Contains the relative or absolute path to your REDCap source folder root (files from Vanderbilt). Must contain the version-specific files for the version you wish to tests against. -
"redcap_version": "13.1.37": Contains the string version of REDCap you want to test against.
The seeds file in this template repository also include a both an admin user and a standard user.
Which user you use to login to REDCap is dependent upon what kind of feature you are intending to test.
To run the tests in the Cypress debug environment, issue the following command at the root of your test folder:
npx cypress open
A Cypress window will open and you can select which specs you'd like to run.
After your test suite is mature, it will be faster to run your tests in headless mode. This is how you would run your tests on a CI server. To do so, issue the following comand:
npx cypress run
