    How to Install Allure Report in Your Project

    Installing Allure Report in a project is a simple process. Here are the basic steps needed to install and generate reports. Keep in mind that you need to adjust the configurations for different projects

    1. First, you need to download and install Allure Commandline. This can be done using npm (Node Package Manager) with the following command: npm install -g allure-commandline --save-dev.
              
    2. Once installed, you can generate Allure Reports using the command: allure generate [allure_output_dir] && allure open. Replace [allure_output_dir] with the directory where your Allure results are stored.

    Sample general steps for Configuring Allure Reports in Google Cloud Platform (GCP)

    While there isn't a direct guide available on the Google Cloud documentation, I can provide a general outline of the steps you would need to follow:

    1. Create a Google Cloud Project: You'll first need to create a new project in the Google Cloud Console. This will provide you with a project ID, which you'll use in subsequent steps.
              
    2. Set up a Compute Engine Instance: You'll need a server to host your Allure Reports. You can do this by setting up a Compute        Engine instance in your Google Cloud project. You'll need to select an operating system for your instance - Allure Reports can run on any system that supports Java, so a Linux-based system like Ubuntu would be a good choice.
              
    3. Install Java: Allure Reports requires Java, so you'll need to install this on your Compute Engine instance. You can do this by connecting to your instance via SSH and running the appropriate commands to install Java.
              
    4. Install Allure Commandline: You'll need to install the Allure Commandline tool on your Compute Engine instance. To do this, download the latest release from the Allure GitHub page and follow the installation instructions.
              
    5. Generate Allure Reports: Once Allure is installed, you can generate reports by running your tests with Allure enabled, and then using the Allure Commandline tool to generate a report. The report will be generated as a set of static HTML files.
              
    6. Serve Allure Reports: To view your Allure Reports, you'll need to serve the static HTML files over HTTP. You can do this by installing a web server like Apache or Nginx on your Compute Engine instance and configuring it to serve your Allure Report files.
              
    7. Access Allure Reports: Once your web server is set up, you can access your Allure Reports by navigating to the external IP address of your Compute Engine instance in a web browser.

     

    Please note that these steps are quite general and the exact commands you'll need to run will depend on the specifics of your setup, such as the operating system you're using and the configuration of your tests. It's also worth noting that while this setup will allow you to view your Allure Reports, it won't automatically update them when new tests are run - you'll need to set up a continuous integration (CI) pipeline to do this. Remember, Allure Report can be integrated into any testing framework, and the installation process may vary slightly depending on the specific framework you are using.

    Possibilities for allure on the example of the cloudia project

    In the Cloudia project we’ve placed an allure server on Google Kubernetes Engine. By doing that, we reuse already existing infrastructure which enables us to expose the server with test reports easily, secure it with Identity-Aware Proxy(IAP) and make it available via web browser.
    The allure pod is also connected to GCS Bucket where we store our test reports. By grouping each test report by typer, date and id, it’s easy to navigate to get the exact test report we are looking for.

    Entering the directory of a particular day there are directories with the test of a particular day. It also depends on our configuration and how many tests will be on a particular day.

    Main allure interface

    Clicking on the selected folder takes you to the allure interface with a report on the individual status of the written tests for the day. In our interface configuration, the main page shows a side menu with many tabs, only some of which will be discussed. In the main area of the interface, you can see the date of the report along with the time it was created, the number of tests and the percentage of tests passed. In addition, you can see our test packages sorted into folders and subfolders, depending on the module being tested. Thanks to the coloring and counting, we have a preview of the status of the tests in each module. There is also a test trend graph, where we can see a preview with the trend of tests by day. In addition, a helpful widget in the interface is categories, where tests that have a defect are visible.

    In this blog post, we will focus on two tabs: Categories, where we can analyze all the defects in our automated tests, and a tab suites, where you can find all the e2e tests we wrote in the playwright framework

    Categories tab

    This tab contains all the defects in our tests. Opening any defect displays information about the selected defect in the interface on the right. In the Overview tab, in addition to the defect itself, we can view the path to the file where the problem occurs. In addition, Allure allows us to trace all the steps in the test body. We can watch a video of our test executing the steps we wrote. We can also download the trace of our tests. In addition, it is possible to preview a screenshot of the place where the test failed to execute further.

    The history tab allows us to preview the status of a particular test with specific dates and times of launch. In addition, the success rate of a given test is calculated.

    The "Retries" tab in Allure reports is used to track and display information about attempts to restart tests that failed the first time.

    Suites tab

    The "Suites" tab in Allure reports is used to present organized information about the test suites that have been performed. "Suite" is a term used to describe a group of tests that are related and are typically run together.

    Under the "Suites" tab, we can see a list of all the test sets that have been run, along with a summary of their results. For each test set, Allure displays the number of tests that passed, that failed, that were skipped, as well as the duration of the entire test set.

    When you click on a specific test suite, you can see detailed information about each test in the suite, including a full description of the test, its status (e.g. success, failure, skip), duration, and any error or exception messages that may have occurred during test execution.

    The "Suites" tab is very useful for quickly reviewing test results and identifying areas that may require additional attention or analysis.

    With tests that have a status of failed, allure proves to be very helpful.

    Allure allows us to preview what is wrong with the test, in addition, it creates a video file that shows the playback of the steps of our written test. This allows us to more quickly locate what could be a potential problem.

    We can also download the entire trace of our test

    Or just see a screenshot of where our test stopped working
