Exploratory Testing is an experience-based test technique involving simultaneous test design and execution. Here's what you need to know about Exploratory Testing as a test engineer:
Definition: Exploratory Testing is a test technique that involves simultaneous test design and test execution, where the tester uses their experience and intuition to identify defects and potential failure modes in the software. This technique is based on the idea that experienced testers can quickly identify possible defects and improve the quality and reliability of the software.
Objective: The main objective of Exploratory Testing is to uncover defects and potential failure modes in the software by using a mix of ad-hoc Testing and structured Testing. The technique aims to be more flexible and responsive to changing requirements compared to traditional scripted Testing.
Process: Exploratory Testing involves using the software in an exploratory and iterative manner, where the tester simultaneously designs and executes tests based on their experience and intuition. Testers may use a combination of techniques, such as boundary testing, equivalence partitioning, and error guessing, to identify potential defects and failure modes.
Advantages: Exploratory Testing can be useful for uncovering defects and potential failure modes that other test techniques may not cover. It is more flexible and responsive to changing requirements than traditional scripted Testing. It can be especially useful in Agile or DevOps environments where there may be frequent changes to the software.
Limitations: Exploratory Testing can be more subjective and dependent on the tester's experience and intuition, leading to inconsistent results. It may also not be an efficient use of testing resources, as it relies on manual exploration of the software rather than systematic testing methods.
Examples: Examples of scenarios where Exploratory Testing may be used include testing a new feature or functionality that has not been previously tested, testing software developed in an Agile or DevOps environment, or testing software with complex or changing requirements.
In conclusion, Exploratory Testing is an experience-based test technique that can be useful for uncovering defects and potential failure modes that other test techniques may not cover. While it may be more systematic and efficient than other testing methods, it can be valuable for experienced testers who deeply understand the software and its potential failure modes. Test engineers should consider using Exploratory Testing with other test techniques to ensure comprehensive software testing.
