This Dockerfile sets up a container for running Selenium tests by copying project files, installing dependencies, and configuring the entry point script to execute the tests.

Run example

npm run import -- "use in Docker"

use in Docker

COPY project /home/seluser/project
COPY selenium /home/seluser/selenium

WORKDIR /home/seluser/project
RUN npm install
RUN npm run build

WORKDIR /home/seluser/selenium/test
RUN npm install

RUN sed -i '/wait \\$NODE_PID/inpm --prefix /home/seluser/selenium/test run static &' /opt/bin/entry_point.sh

bash
# Set working directory to /home/seluser
WORKDIR /home/seluser

# Create project and selenium directories
RUN mkdir -p project selenium

# Copy project and selenium directories to the new locations
COPY project /home/seluser/project
COPY selenium /home/seluser/selenium

# Switch to project directory
WORKDIR /home/seluser/project

# Install dependencies and build the project in a single command
RUN (cd /home/seluser/project && npm install && npm run build)

# Switch to selenium/test directory
WORKDIR /home/seluser/selenium/test

# Install npm dependencies in selenium/test directory
RUN npm install

# Edit entry_point.sh file to add npm run static command
RUN sed -i '/wait \$NODE_PID/)s/$/ && npm --prefix /home/seluser/selenium/test run static/' /opt/bin/entry_point.sh

# TODO: Consider using a more robust method for modifying the entry_point.sh file, such as using a template file.

This Dockerfile snippet sets up a development environment for a Selenium project within a Docker container.

Here's a breakdown:

1. Copy Project Files:

   • COPY project /home/seluser/project: Copies a directory named "project" from the build context (your local machine) into the /home/seluser/project directory within the container.
   • COPY selenium /home/seluser/selenium: Copies a directory named "selenium" from the build context into the /home/seluser/selenium directory within the container.

2. Set Working Directory:

   • WORKDIR /home/seluser/project: Sets the working directory for subsequent commands to /home/seluser/project.

3. Install Project Dependencies:

   • RUN npm install: Installs project dependencies within the /home/seluser/project directory using npm.
   • RUN npm run build: Executes the "build" script defined in the project's package.json file, likely to compile or prepare the project for deployment.

4. Switch to Selenium Directory:

   • WORKDIR /home/seluser/selenium/test: Changes the working directory to /home/seluser/selenium/test.

5. Install Selenium Dependencies:

   • RUN npm install: Installs dependencies for the Selenium tests within the /home/seluser/selenium/test directory.

6. Modify Entry Point Script:

   • RUN sed -i '/wait \\$NODE_PID/inpm --prefix /home/seluser/selenium/test run static &' /opt/bin/entry_point.sh: Modifies a script named entry_point.sh located at /opt/bin/entry_point.sh. It likely adds a command to run Selenium tests using npm within the /home/seluser/selenium/test directory.

In essence, this Dockerfile prepares a containerized environment for running Selenium tests by installing dependencies, building the project, and configuring the entry point script to execute the tests.
