Test Automation Coexists Well with Exploratory Testing

In exploratory testing, the tester analyses the software system without utilizing a formal test plan or script and instead relies on their expertise and intuition to spot any flaws. It is notably helpful for detecting brand-new, unforeseen problems as well as weaknesses that less formal testing methods can overlook. Also, it is a fantastic technique to evaluate user experience and assess the software from the viewpoint of the user.

On the other hand, end-to-end automated regression testing is a more formalized method of testing that uses automated testing tools and scripts to conduct a series of pre-defined tests on the program. Ensuring that new software system additions do not negatively impact its functionality is a crucial part of software testing. After changes have been made, a series of automated tests must be run to verify that the software operates as expected.

Here are the top 10 reasons we believe that reliable automated end-to-end regression testing is crucial for software testing and that, in the absence of it, exploratory testing can be jeopardized:

1. Coverage: Automatic end-to-end regression testing can examine a wide range of situations, giving full coverage of the software’s functionality. Potential problems could go unnoticed during exploratory testing if certain conditions or components of the product are not examined.
2. Precision: As automated end-to-end regression testing is not subject to human biases, errors, or oversights, it can produce more accurate and dependable results. Exploratory testing can be subjective and based on the tester’s perception, which might produce incorrect results or lack valuable information.
3. Scalability: Automated end-to-end regression testing can scale up or down depending on the program’s complexity and the project’s demands. Especially for large and complicated software systems, exploratory testing cannot be scalable as it can be difficult to test all the functionality manually.
4. Uniformity: Automated end-to-end regression testing guarantees consistency in the testing process by ensuring that the same tests are rerun. Exploratory testing relies heavily on the tester’s knowledge and judgment, which makes it challenging to conduct tests consistently.
5. Human error: Exploratory testing is more likely to involve human mistakes, which could lead to overlooked flaws or false positives. By conducting tests regularly and accurately, automated end-to-end regression testing can help lower the chance of human mistakes.
6. Maintenance: Maintaining test suites as the software develops without automated end-to-end regression testing might be difficult. Exploratory testing’s effectiveness may be jeopardized if it takes a lot of work to keep up with software updates.
7. Continuous Integration and Delivery: Integrating testing into a continuous integration and delivery (CI/CD) pipeline can be problematic without automated end-to-end regression testing. Because of its nature, exploratory testing does not fit into a CI/CD pipeline, which could slow down software delivery and reduce its efficacy.
8. Timesaving: Automated end-to-end regression testing can save time and effort by swiftly completing a substantial number of tests. Conversely, exploratory testing may take a long time and require a lot of work to find and recreate problems.
9. Cost-effectiveness: Automatic end-to-end regression testing reduces the requirement for manual testing and lowers the likelihood of software flaws, both of which can result in cost savings. Exploratory testing may sometimes offer a different amount of coverage than automated testing and can be expensive, mainly when performed in detail. We agree that automated testing, however, might only be able to catch some potential problems and might take a lot of time and money to set up and maintain, but it is very cost-effective eventually.
10. Risk reduction: Automated end-to-end regression testing helps reduce the risk of software failures by ensuring that new modifications do not impact existing functionality. Exploratory testing may not offer the same level of risk reduction as automated testing, but it can assist in uncovering potential problems.

In conclusion, exploratory testing and automated end-to-end regression testing are two different approaches to software testing with their own unique advantages and disadvantages. While exploratory testing might offer insightful information about software problems, more is needed to replace reliable automated end-to-end regression testing. Automated end-to-end regression testing is necessary to guarantee thorough and trustworthy testing of software systems. Using both forms of testing can assist assure complete and reliable software testing.
