Berg

Berg is a test-suite for HAL Management Console based on Cypress UI test automation. Berg as a name is heavily inspired by Gutenberg, inventor of printing press :) (printing press -> press -> Cypress).

Technological Stack

NodeJS

Node (https://nodejs.org/en/) is the JavaScript runtime engine used to run Berg, since Cypress is built only for JavaScript.

Cypress

Cypress (https://www.cypress.io) is the main automation framework used for developing, running & reporting tests. Main benefit of Cypress is, that it is bundling the testing code directly into the system (browser) under testing. Since JavaScript is the main language used by modern browsers, the test execution is swift, stable and less environment error-prone as in standard (Selenium + WebDriver) UI automation tools.

TestContainers

TestContainers (https://github.com/testcontainers/testcontainers-node) serves to launch & manage test scoped containers. Currently following containers are being used for testing:

• Standalone HAL image used for most of the UI testing. It is a standalone HAL binary delivered by a container image that will be connected to a running WildFly server (that exposes management interface)
• WildFly Server Image used for resource management. Exposes management interfaces onto which the Standalone HAL Image connects.
• DB Images (such as postgres) serving (mostly) to run DB instances, that are being used in the datasource related tests.

Requirements

Following tools are required to run the test suite

• NodeJS as a runtime environment
  • recommended version is 16, in other versions you can get errors like Unable to detect compiler type
  • Node Version Manager (nvm) is recommended optional tool to install & manage multiple Node environments
• npx CLI tool used to exeute binaries from project's node_modules directly (instead of providing absolute/relative path to the commannds). It is used in multiple build steps.
• Podman | Docker as a container runtime used by TestContainers. Note that when using Podman as container runtime you may need to export following environment variables and start podman socket:
  • export TESTCONTAINERS_RYUK_DISABLED=true
  • export DOCKER_HOST=unix:///run/user/$UID/podman/podman.sock
    • the path can be found by command podman info --debug and look for path in remoteSocket section.
  • systemctl --user start podman.socket
• Java. Yes we'll need Java to write deployments/applications that will be deployed onto the running WildFly container.
• Maven. Yes, we'll need Maven to ease up the development of the deployed applications & downloading needed JDBC drivers for datasource & drivers UI tests. Maven is mostly used embedded by node-maven JS wrapper to execute Maven & Java related tasks into the build automation.

How to build & run

• Make sure you have all the tools from Requirements installed
• Run

npm install

in the root directory to download all of the NPM dependencies specified in package.json

• If you want to run Cypress developer console with the loaded spec files, run

npm run develop

• If you want to execute whole testsuite, navigate to packages/testsuite and from within that directory execute npm test
  • It is also possible to run on specific browser by supplying --browser argument, e.g

  npm test -- --browser=chrome
  

  • It is also possible to reduce the amount of specs executed by passing --specs flag. This flag must be relative to the packages/testsuite directory and supports glob patterns, e.g to execute only ejb related tests, run

  npm test -- --specs="cypress/e2e/ejb/*.cy.ts"
  

  • If you wish to run the test suite against custom HAL or WildFly images, you can use HAL_IMAGE and WILDFLY_IMAGE environment variables to specify custom images, e.g

  HAL_IMAGE=quay.io/myorg/hal WILDFLY_IMAGE=quay.io/myorg/wildfly npm test ...
  

Available environment properties

Following is a table of supported environment properties that can be used when running the testsuite.

Property name	Default value	Description
HAL_IMAGE	quay.io/halconsole/hal-development:latest	HAL standalone image to be used
WILDFLY_IMAGE	quay.io/halconsole/wildfly-development:latest	WildFly/JBoss EAP image to be used
KEYCLOAK_IMAGE	quay.io/keycloak/keycloak:latest	Keycloak/RH-SSO image to be used for OIDC tests
POSTGRES_IMAGE	docker.io/library/postgres:latest	PostgreSQL image to be used for datasource tests
MYSQL_IMAGE	docker.io/library/mysql:latest	MySQL image to be used for datasource tests
MARIADB_IMAGE	docker.io/library/mariadb:latest	MariaDB image to be used for datasource tests
MSSQL_IMAGE	mcr.microsoft.com/mssql/server:2022-latest	Microsoft SQL Server image to be used for datasource tests
