A few days ago, I was trying to set up Jasmine to output the description of the tests while running it. It wasn’t as straightforward as passing in a command line argument, so I turned to everyone’s favorite boogeyman, ChatGPT, to help. Here is the complete conversation: https://gpt.best/c0JV9sJt. TLDR: It helped, but I had to hand-hold it a few times.
In the end, I asked ChatGPT to generate a blog post with my findings, and here’s what it outputted.
When working with Jasmine for testing JavaScript applications, you may want to have a global configuration that automatically includes a custom reporter, such as jasmine-spec-reporter, for all your projects. This blog post will guide you through the process of setting up a global Jasmine configuration file and using the custom reporter to display test results in a more human-readable format.
Step 1: Install jasmine-spec-reporter
First, you’ll need to install the jasmine-spec-reporter package globally:
npm install -g jasmine-spec-reporter
Step 2: Create a global Jasmine configuration file
Next, create a global Jasmine configuration file named jasmine-global.json. You can store this file in a convenient location, such as your home directory. In this file, specify the helpers key with an absolute path to a custom helper file that will configure the reporter:
{
"helpers": ["/path/to/your/req-jasmine-reporter.js"]
}
Replace /path/to/your with the correct path to the directory where you’ll store the req-jasmine-reporter.js file.
Step 3: Create the custom helper file
Now, create a file named req-jasmine-reporter.js in the directory specified in the previous step. This file will configure the jasmine-spec-reporter. Add the following code to the file:
const SpecReporter = require('jasmine-spec-reporter').SpecReporter;
jasmine.getEnv().clearReporters();
jasmine.getEnv().addReporter(new SpecReporter({
spec: {
displayPending: true,
displayStacktrace: 'specs'
}
}));
Step 4: Set the JASMINE_CONFIG_PATH environment variable
To tell Jasmine to use your global configuration file, set an environment variable named JASMINE_CONFIG_PATH to the path of your jasmine-global.json file.
For Unix-based systems, add the following line to your shell profile file (e.g., .bashrc, .bash_profile, .zshrc, etc.):
export JASMINE_CONFIG_PATH="/path/to/your/jasmine-global.json"
For Windows, open the Environment Variables dialog (search for “Environment Variables” in the Start menu) and add a new user or system variable named JASMINE_CONFIG_PATH with the value set to the path of your jasmine-global.json file.
Step 5: Run Jasmine tests with the custom reporter
Now, when you run Jasmine tests using the command npx jasmine
Conclusion:
By following these steps, you can create a global Jasmine configuration that includes a custom reporter for all your projects. This setup can help you maintain consistent test output formatting and streamline your testing process. Keep in mind that using a global configuration may not be suitable for every project, especially when working with multiple developers or projects with different dependencies. In such cases, it’s recommended to maintain separate configurations for each project.
The resulting blog post is boring, to the point and devoid of personality, but it gets the job done.
