Base para hacer tests

Configuración básica para empezar a hacer una kata o aprender a hacer tests en los siguientes lenguajes:

• PHP y PHPUnit
• Javascript con Jest
• Typescript con Deno
• Java, Junit y Mockito
• Scala, Munit y Scalacheck
• Kotlin, JUnit5 y MockK
• C#, xUnit (con FluentAsertion) y NSubstitute (para mock)

Configuración específica por lenguaje

PHP

1. Instalar composer curl -sS https://getcomposer.org/installer | php
2. composer install (estando en la carpeta php)
3. ./vendor/bin/phpunit

Javascript

1. Instalar Node
2. npm install (Estando en la carpeta javascript)
3. npm test

Typescript

1. Instalar Deno
2. deno test (Estando en la carpeta typescript)

Java

1. Instalar las dependencias y tests con Maven [mvn test]
2. Ejecutar los tests con el IDE

Scala

1. sbt (en la carpeta scala)
2. ~test para ejecutar los test en hot reload

Linux/Mac

1. Instalar SDKMan
2. sdk install java 11.0.12-open instala OpenJDK
3. sdk install sbt una vez instalado SDKMan

Windows

1. Instalar OpenJDK
2. Instalar SBT

Visual Studio Code

1. Descargar Visual Studio Code
2. Instalar para VS Code Metals

Kotlin

1. Por consola: Puedes instalar dependencias y lanzar los tests con gradlew test
2. Usando IDE: Simplemente abre el proyecto desde el raiz de la plantilla Kotlin

C#

2. Abre el proyecto y se descargaran automáticamente los paquetes Nuguet necesarios

Python

1. Instalar python 3.x
2. Una vez descargado el código fuente dentro de la carpeta */python/ creamos un virtual enviroment:
3. python3 -m venv env
4. Activamos en virtual environment:

• windows: .\env\Scripts\activate.bat
• linux/mac: source env/bin/activate

5. pytest para ejecutar los tests.
