Introduction to Exploratory Testing:
Exploratory testing is a method of testing that emphasizes the tester’s freedom and creativity to design and execute tests. It is an approach that is best suited for situations where there is little to no documentation or specifications, or the requirements are constantly changing. It is an intuitive approach to testing that leverages the tester’s skill and expertise to find and report defects.
Types of Exploratory Testing:
- Freestyle Testing: Freestyle testing is an unstructured approach that involves ad hoc testing, where testers use their knowledge and experience to identify defects.
- Strategy-based Testing: Strategy-based exploratory testing is a structured approach that involves following a predefined strategy or test plan.
- Scenario-based Testing: Scenario-based exploratory testing involves identifying and executing test scenarios based on specific user scenarios or workflows.
History of Testing:
It has been around for many years and was first introduced in the early 1990s by Cem Kaner. Since then, it has become a widely accepted approach to testing in the software industry.
Scientific Studies on Testing:
Several scientific studies have been conducted on exploratory testing. One study found that it was more effective in finding defects than scripted testing. Another study found that it was more effective in identifying usability issues.
Exploratory Testing Techniques:
Some of the techniques used in exploratory testing include ad hoc testing, session-based testing, and touring-based testing.
How to Execute Exploratory Tests:
The following are the steps involved in executing exploratory tests:
Step 1) Create a Bug Taxonomy (classification): Create a classification system for defects that are identified during testing.
Step 2) Test Charter: Define the objectives, scope, and constraints of the testing session.
Step 3) Time Box: Define a time limit for the testing session.
Step 4) Review Results: Review the results of the testing session and document any defects found.
Step 5) Debriefing: Conduct a debriefing session to discuss the results of the testing session.
Why Use it?
Ig is useful in situations where the requirements are constantly changing or there is little to no documentation or specifications. It is also useful in identifying defects that may not be found through scripted testing.
When Should You Use it?
It should be used when the requirements are unclear or when there is little to no documentation or specifications. It is also useful in situations where there is a need to identify defects quickly.
When to Say No to Testing?
It may not be suitable for situations where there is a need for repeatable, automated tests, or where the requirements are well-defined and documented.
Importance of Exploratory Testing for CI/CD:
It is important for CI/CD because it allows for quick and efficient testing of software changes. It is also useful in identifying defects that may not be found through automated testing.
Best Practice Exploratory Testing:
Some best practices for it include setting clear objectives, defining a time limit for the testing session, and documenting defects found.
Pros and Cons of Exploratory Testing:
Pros:
- More effective in finding defects than scripted testing.
- Allows for quick and efficient testing of software changes.
- Useful in identifying defects that may not be found through automated testing.
Cons:
- Requires skilled testers.
- Results may not be repeatable or easily automated.
- May not be suitable for all types of testing.
Challenges of Exploratory Testing:
Some challenges of this include the need for skilled testers, the difficulty in measuring the effectiveness of testing, and the potential for bias.
Proper Conclusion:
Exploratory testing is a valuable approach to software testing that allows testers to use their intuition and creativity to identify defects. It is useful in situations where requirements are unclear, or there is little to no documentation. It can be performed in different ways, including freestyle, strategy-based, and scenario-based testing. It can be executed using techniques such as ad hoc testing, session-based testing, and touring-based testing.
Executing exploratory testing involves defining objectives, scope, and constraints, setting time limits, and documenting defects found. testing is essential for continuous integration and delivery, as it enables quick and efficient testing of software changes.
Although it has many benefits, it also has its challenges, such as the need for skilled testers and the difficulty in measuring the effectiveness of testing. Despite these challenges, it remains a valuable approach to software testing and should be included in every testing strategy.
Overall, it is an important approach to software testing that complements scripted testing and helps organizations deliver high-quality software. It provides flexibility and agility in testing and helps organizations identify defects that may be missed through other testing methods. By embracing it, organizations can improve the quality and reliability of their software products.
