Q & A

What is the core concept of exploratory testing?
-The core concept of exploratory testing is that it is a type of testing that is controlled by the tester, allowing them to make choices and exercise their critical thinking skills during the testing process.
Why is the term 'exploratory testing' unique in the context of testing jobs?
-The term 'exploratory testing' is unique because it highlights the fact that testers, unlike in many other professions, are often expected to follow predefined scripts and not make independent choices, which is unusual for roles that require intelligence and problem-solving skills.
What does it mean for a tester to have control during testing?
-Having control during testing means that the tester has the autonomy to decide what to test, how to test it, and when to make changes or stop testing, based on their observations and understanding of the software being tested.
Why would a tester ever choose to give up control during testing?
-A tester might choose to give up control during testing to adhere to strict guidelines or regulatory requirements, or when using scripted testing methods that are more suitable for certain types of testing, such as compliance-based or accessibility testing.
How does the perception of testers as 'stupid' affect the industry?
-The perception of testers as 'stupid' or less intelligent leads to an undervaluation of their critical thinking and problem-solving abilities, which in turn can result in a preference for scripted testing over more dynamic and adaptable exploratory testing methods.
What is the role of intelligence and adaptability in exploratory testing?
-Intelligence and adaptability are crucial in exploratory testing as it requires testers to think on their feet, make informed decisions, and adapt their approach based on the outcomes of their testing and the behavior of the software under test.
How does exploratory testing differ from scripted testing?
-Exploratory testing involves simultaneous test design and execution, with a focus on discovery and learning, whereas scripted testing follows predefined test cases and is more structured and less flexible.
What are some benefits of exploratory testing?
-Benefits of exploratory testing include the ability to uncover bugs that may be missed by other testing methods, the flexibility to adapt to new findings, and the encouragement of creativity and critical thinking among testers.
What are some challenges associated with exploratory testing?
-Challenges of exploratory testing include difficulties in replicating failures, determining the need for tools, selecting the best test cases, reporting test results, and documenting all events during execution.
In what situations might exploratory testing be particularly useful?
-Exploratory testing can be particularly useful when there are experienced testers on the team, when an early iteration is required, when testing a critical application, or when introducing new testers to the team.
How does the industry's view of testers affect the use of exploratory testing?
-The industry's view of testers as mere executioners of scripts rather than intelligent professionals can lead to underutilization of exploratory testing, which relies on the tester's ability to make informed choices and adapt to the software's behavior.

Keywords

💡exploratory testing

Exploratory testing refers to an approach in software testing where the tester actively controls the testing process, making decisions on what to test and how to test it based on their experience and intuition. This method emphasizes the importance of the tester's ability to adapt and make choices in real-time, as opposed to following a predetermined script. In the video, it is highlighted as the fundamental idea that empowers testers to act as intelligent individuals, using their brains to make informed decisions during the testing process.

💡tester

A tester in the context of the video is a professional who is responsible for evaluating the quality of a product or system, particularly software. The role of a tester is not just to execute tests but to engage in exploratory testing, which requires critical thinking, problem-solving skills, and the ability to make choices. The video emphasizes that testers should not be seen as mere executors of test scripts but as knowledgeable individuals who can contribute significantly to the quality assurance process through their expertise and decision-making capabilities.

💡human algorithm

The term 'human algorithm' in the video script refers to the notion that when testers stop being exploratory and simply follow a predetermined script, they become akin to a human algorithm—executing instructions without the benefit of human intuition and decision-making. This concept is used to criticize the devaluation of the tester's role and to argue for the importance of exploratory testing, which leverages the tester's cognitive abilities and adaptability.

💡power to make choices

The 'power to make choices' is a central theme in the video, highlighting the importance of agency and autonomy in the testing process.
