Automate anything, Run Anywhere is our motto!

What better place to start making it real than from our very own Workload Automation test environment?

We have been applying it in our Test Lab for Workload Automation version 9.5 since its general availability in 2019, and to all the subsequent fix packs, including the last one, fix pack 3.

Let’s start discovering how we can leverage a Workload Automation deployment to run automation jobs that build our code and prepare packages for both our HCL and IBM brand offerings. The automation jobs trigger several automation suites running for each brand.

Every day, we run about 20,000 automated test scenarios that cover all the Workload Automation components (Dynamic Workload Console, master domain manager and its backup, the Rest APIs layer, dynamic agents and fault-tolerant agents).

Rest assured that we always uphold backward compatibility and detect instability issues before, rather than later! The main goal for us is to prevent injecting defects and instability to the base functionalities used by the most part of our customers.

Let’s take a deep dive into the automation world!

How many test automation suites?

how many test automation suite

Fig. 1 – Automation suites daily flow

 

The Workload Automation solution includes the following test automation suites:

  • BVT suites (Build Verification test that validates the health of the most recent available product component packages)
  • Installation and upgrade suite
  • Rest APIs suite
  • Dynamic Workload Console (web-based User Interface) suite
  • Server suite
  • Agent suite

 

The latest results of the automation suites are available on our Jenkins site and they are gathered in theAggregate Test Report. The Aggregate Test Report is a giant matrix where each row represents a Jenkins job that groups a list of test scenarios belonging to a specific suite and the columns correspond to the date when the Jenkins job runs. The color of each cell of the Aggregate Test Report is updated each time the Jenkins job completes its daily or weekly run. The color indicates the percentage of failed test cases with respect to the total number of them.

The matrix has continually evolved since the test phase of the version 9.5 General Availability through until the test phase of the latest fix pack.

Let’s figure out the number of the scenarios that automatically run every day for each automation suite.

What is the flow of the daily WA test automation suites?

 

continous testing journey

Fig. 11 – Detailed Continuous testing journey

 

Every day, when a new product build is available, the automatic Jenkins workflow starts and performs the following steps:

  • The code for the test automation suites is extracted from the code repository (GitHub) and then a build for each test automation suite is performed.
  • The Workload Automation daily build and the build for the test automation suites are combined into the test repository.
  • The Workload Automation daily build is installed automatically on all the test machines that are part of the test automation infrastructure.
  • The test automation suites are deployed automatically on all the test machines that are part of the test automation infrastructure.
  • The execution of the test automation suites is invoked automatically.
  • At the end of each execution of the test automation suites, test logs are collected, and test results are published on the Jenkins Aggregate Report to be analysed by a test automation specialist.

 

During the development phase (when the new product features are developed), the test automation suites are enriched to also cover the features that are being developed over time. The main objective of test automation during this phase is to increase the test coverage to include the new functionalities that are being added in the product version under test.

During the formal System Verification Test (SVT) phase, the new test automation test cases, that were created during the development phase, are merged into the pre-existing test automation suites.

The daily runs of these enriched test automation suites check the stability of the code, gain greater coverage as new tests are added to the regression package, and reduce test time compared to manual testing. The main objective of test automation during this phase is to demonstrate the stability of the product and to prevent potential backward compatibility issues affecting ideally the base features.

 

At the end of this journey, there is specific success criteria that must be met to consider the quality of the product good enough to be released on the market and that is, the single test automation suites must have a success rate that is higher than the results obtained for the previous release:

 

At the end of the Workload Automation 9.5 Fix Pack 3 development cycle, the success criteria were satisfied with the following values:

  • Dynamic Workload Console suite success rate: 100%
  • Installation suite success rate: 100%
  • Rest API Suite success rate: 99%
  • Agent suite success rate: 99%
  • Server suite success rate: 99%

 

Moreover, the test automation framework described in this article allowed the Workload Automation team to find and fix around 240 defects during the 9.5 Fix Pack 3 development cycle.

 

We hope this article is helpful in understanding the ecosystem in which the WA solution shapes up and evolves to satisfy our customer needs.
