Automate tasks in software testing

When the term automation is mentioned, it is common for people to think of automated tests. But, time and effort can also be saved by automating other tasks such as generating test data and reporting test results automatically. A few factors should be considered for effectively deciding whether to automate a task or not. Last year, we had fruitful discussions on this topic within the STS group.

Let us see some candidate tasks for automation. Testers spend a lot of time on these tasks. If such tasks are fully or partially automated, the saved time can be spent on testing the system.

1. Test identification based on risk or other factors
List all the available test cases along with related features, components and priorities. The automation can take the inputs e.g. impacted features and generate the list of test cases that should be executed on the new application build.

2. Test estimation
Automation can be used to help estimate the test effort and duration. This can be done based on the preferred estimation approach. Whether by querying the historical data for actual efforts and durations, or by applying a custom formula to estimate test effort and test duration.

3. Generation of test data
Build a library of business rules for your test data. Build the initial seed data manually. The automation can use the seed data and generate test data based on the chosen business rules. Since test data generation is usually consumes much time, the automated generation can be performed ahead of time. Then, the pre-generated test data can be used directly during test execution.

4. Generation of bug reports
This automation can be built into the test automation framework. Whenever an automated test script confirms an error, it logs into the bug tracking system and reports a bug with required information. Such as bug title, steps to reproduce, test data used, environment used and so on.

5. Generation of test reports
This automation can execute queries against the test management system (and bug tracking system, if different) and generate test reports. Even distribute them by email or publishing to a website.

6. Release notes preparation
Release notes contain both static and dynamic data. This automation can execute queries on the test management system to retrieve the dynamic data such as features passed, bug fixes passed and known bugs.

Before prioritizing the automation development, always analyze the following factors.
a. Degree of automation achievable
b. Skills required to automate
c. Effort required to automate
d. Number of proposed users
e. Effort required to train users
f. Effort required to execute automation
g. Effort required to maintain automation
h. [Important] Manual effort saved

In the future, I see a number of such tasks automated with the help of vendor tools or bespoke in-house automation.
Let me know if you liked this post. I would love to know your thoughts on this topic.
