`Introduction to` `SDET Interview Questions`

Explore the latest SDET Interview Questions of 2023, designed to test your technical prowess and problem-solving skills. Prepare for success in the ever-evolving field of Software Development Engineering in Test (SDET).

1. Differentiate between Software Development Engineer in Test (SDET) and Manual Tester.

SDET: Automates tests, codes, and focuses on tooling for efficient testing.

Manual Tester: Conducts tests manually, emphasizing human observation and validation.

2. What do you understand about ad-hoc testing?

Ad hoc testing is an ordinarily involved term for arranged programming testing that is performed without starting experiment documentation; nonetheless, impromptu testing can likewise be applied to other logical examination and quality control endeavors.

3. What do you understand about code inspection in the context of software testing? What are its advantages?

Code assessment in programming is the most common way of evaluating the code in an application to check for deserts. Its motivation is to address the issues in the programming language so the product performs at its most noteworthy potential.

4. What is a bug report in the context of software testing?

A bug report in QA is a record that portrays an issue or deformity in a product application. It regularly incorporates the climate, moves toward repeat the issue, and expected versus genuine way of behaving.

5. What are the elements of a bug report?

A powerful bug report will incorporate a title, bug depiction, climate data, moves toward recreate, and that’s just the beginning — so engineers can replicate and fix the issue.

6. What are the do’s and don'ts for a good bug report?

Do’s:

Provide a clear issue description.
Include steps to reproduce.
Specify the expected vs. actual behavior.
Attach screenshots or logs if helpful.
Mention the environment and version.

Don’ts:

Avoid vague or ambiguous descriptions.
Don’t skip essential details.
Refrain from using subjective terms.
Don’t assume the developer’s perspective.
Avoid attaching unnecessary files.

7. What are the roles and responsibilities of a Software Development Engineer in Test (SDET)?

SDET Responsibilities:

Test Automation: Develop automation frameworks for diverse platforms.
Customer Issue Resolution: Investigate and address technical support-referred problems.
Bug Management: Create, manage, and communicate bug reports within the team.
Research: Explore test data, automation tools, and industry trends.
Process Enhancement: Upgrade existing practices for efficiency.
Tool Creation: Develop tools and frameworks for testing across platforms.
Coding Support: Assist in writing, running, and maintaining product and test codes.
CI/CD Implementation: Build CI/CD pipelines for seamless development.
Design Input: Contribute to product design discussions for enhanced testability.
Behavior Driven Development: Apply coding expertise for effective automated test scripts.

8. What do you understand about severity and priority in the context of software testing? Differentiate between them.

In software testing, severity is a parameter that describes how much a defect affects the software’s functionality. Priority is a parameter that determines the order in which defects should be fixed.

Severity is more objective, while priority is more subjective. Severity is about the technical impact of an issue on the system. Priority is about the business impact.

9. What do you understand about alpha testing? What are its objectives?

Alpha testing is a type of user acceptance testing that’s done before a product is released to the public. The main objectives of alpha testing are:

To identify and fix bugs that were not discovered in previous tests
To evaluate the software’s overall performance, functionality, and usability
To ensure that the software is functional, reliable, and free of any defects or errors

Alpha testing is typically performed by in-house software engineers or QA staff. It’s usually the first phase of testing and involves testing the software in a controlled environment. Alpha testing generally attempts to simulate real user behavior by using black and white box testing techniques.

Alpha testing is done to:

Refine the software product
Give better insight into the software’s reliability at the early stages of development
Make sure a product is ready to send to potential end-users for beta testing

10. What do you understand about beta testing? What are the different types of beta testing?

Beta Testing: Definition: Testing performed by end-users in a real environment before software release. Objectives:

User Feedback: Gather insights from real-world users.
Identify Bugs: Detect defects not found in earlier testing phases.
Evaluate Usability: Assess the software’s user-friendliness.

Types of Beta Testing:

Open Beta: Public release for a wide user base.
Closed Beta: Limited release to a specific user group.
Post-Release Beta: Continuous testing after the official release.
