As its name implies, functional testing is the process of validating an application to the requirements in the requirement document.
Functional testing services may be conducted manually or automatically, but each method comprises evaluating the application by giving a set of inputs and determining or validating the result/output by comparing the actual result to the intended result.
Popular Interview Questions On Functional Testing
- Describe In Detail What You Understand The Word “functional Testing” To Mean.
Functional testing is a black box testing approach where the functionality of an application is evaluated to create the required result by supplying specific input.
In addition to validating that the program’s behavior conforms to the requirements document’s specifications, the purpose of functional testing is to determine if the application is prepared for deployment into the live environment.
- What Are The Essential Processes Included In Functional Testing?
As Part Of Functional Testing, The Following Procedures Should Be Covered:
- Comprehending the Requirement document’s requirements and resolving any questions or concerns in the form of review comments.
- Creating test cases in accordance with the required definition while keeping in mind all of the situations that must be evaluated for each instance.
- Identifying the test inputs and obtaining the test data necessary to perform the test cases and verify the application’s operation.
- Determine the real consequences based on the tested input values.
- Execute the test cases that assess if the application behaves as anticipated or if any defects exist.
- Compare the real result with the calculated result to determine the actual result.
- How Does “Build” Differ From “Release”?
The build is an executable file referring to the portion of a program that is sent to a tester to test the implemented functionality of the application along with problem fixes. The build may be rejected by the testing team if it fails to pass the critical checklist, which consists of the application’s most important features.
Multiple builds are possible throughout the testing phase of an application.
The release refers to a software program that is no longer in the testing phase and is delivered to the customer upon completion of testing and development. One release is connected with many builds.
- Explain The Bug Life Cycle.
A bug is an error, fault, or mistake that has occurred inside a program and stops it from producing the correct result. When a defect or bug is discovered in an application during testing, it through a certain life cycle, known as the Bug Lifecycle, from defect tracking to resolution.
- Include The Bug Status And Its Explanation.
Listed Below Are Many Bug Statuses And Their Respective Descriptions:
- When a flaw or problem is reported for the first time, it is referred to as “New.”
- After the tester has reported an issue, the bug is examined by the tester lead and then allocated to the appropriate programming team.
- Open: A tester files an issue in the Open state, where it stays until a developer has completed a job on it.
- Resolved/Fixed: When a developer has fixed a problem, i.e., the program is now delivering the intended result for a specific issue, he or she updates the bug’s status to Resolved/Fixed.
- Verified/Closed: When a developer changes the status to resolved/fixed, the tester verifies the problem and, if it is resolved, changes the status to “Verified/Closed.”
- Reopen: If a tester is able to replicate the problem after the developer has fixed it, indicating that the bug still exists, the bug’s status is changed to Reopen.
- Not a bug/Invalid: A developer may designate a problem as invalid or not a bug when the reported issue is consistent with the functionality but was incorrectly filed due to a misunderstanding.
- If there is a shortage of time and the problem has a low priority for the release, it is often delayed until the following release.
- Cannot Replicate – If the developer is unable to reproduce the problem at their end using the techniques outlined in the issue.
These are some of the most common questions you may be asked/heard when hiring a dedicated QA team.
