How do you test pagination, sorting and filtering through an API?

AdobeMedium
Save to ▾

Send page, size, sort and filter parameters, then verify counts, order, boundaries (first, last, empty page) and invalid parameter handling.
03

How do you test a REST API with authentication?

AdobeMedium
Save to ▾
Show answer
Check access with valid, expired and missing tokens, role-based permissions, error codes and that sensitive data is never exposed.
04

Release is tomorrow and you can't test everything. What now?

AdobeHard
Save to ▾
Show answer
Risk-based testing: cover critical user flows, recent changes and high-defect areas first. Clearly communicate the untested risks and get stakeholder sign-off.
05

Production has a critical bug. What are your steps?

AdobeHard
Save to ▾
Show answer
Reproduce and assess impact, inform stakeholders, help developers fix and verify in staging, run regression and check monitoring after the hotfix, then do a post-mortem.
06

What are the seven principles of testing?

AdobeMedium
Save to ▾
Show answer
Testing shows presence of defects, exhaustive testing is impossible, test early, defects cluster, the pesticide paradox, testing is context-dependent and absence-of-errors is a fallacy.
07

How do you test an application when requirements change frequently?

AdobeMedium
Save to ▾
Show answer
Keep tests modular, prioritise by risk, use exploratory testing, automate stable parts and keep close contact with product owners.
08

What is Agile testing?

AdobeEasy
Save to ▾
Show answer
Testing that is continuous and collaborative within each sprint, with testers working alongside developers and product owners from the start.
09

Save to ▾
Show answer
Basic operations, division by zero, decimals, large numbers, order of operations, clear and backspace, repeated operations and memory keys.
14

Verification vs validation?

AdobeEasy
Save to ▾
Show answer
Verification: are we building the product right? (reviews, walkthroughs — no code run). Validation: are we building the right product? (actual testing against user needs).
15

Save to ▾
Show answer
JIRA Query Language, used to search issues, for example project = ABC AND status = Open AND priority = High.
16

How do you estimate testing effort?

AdobeHard
Save to ▾
Show answer
Break the work into modules and test cases, use past velocity or three-point estimation (optimistic, likely, pessimistic), add time for test data, environment issues, retesting and regression, and keep a risk buffer.
17

What is UAT?

AdobeEasy
Save to ▾
Show answer
User Acceptance Testing — end users or the client verify that the system meets business needs in a production-like environment before go-live.
18

Show answer
New → Assigned → Open → Fixed → Retest → Verified → Closed, with Reopened, Rejected, Deferred and Duplicate as side paths.
22

What is API testing and why is it important?

AdobeMedium
Save to ▾
Show answer
Testing services directly without the UI, checking status codes, responses, security and performance. It finds issues early and is faster than UI tests.
23

AdobeMedium
Save to ▾
Show answer
Re-check the requirement, reproduce with clear steps and evidence (screenshots, logs), discuss with the BA/PO and record the final decision.
24

What is the difference between a test case and a test scenario?

AdobeEasy
Save to ▾
Show answer
A scenario is a high-level thing to test (user logs in); test cases are the detailed steps and data that verify it.
25

What are the characteristics of a good test case?

AdobeMedium
Save to ▾
Show answer
Clear, concise, independent, repeatable, traceable to a requirement, with precise expected results and tested data.
26

AdobeMedium
Save to ▾
Show answer
Valid transfer, insufficient balance, daily limit, wrong beneficiary, OTP failure, network drop mid-transaction, duplicate click and statement update.
27

AdobeMedium
Save to ▾
Show answer
Test execution rate, pass percentage, defect density, defect leakage, defect rejection ratio, requirement coverage and automation coverage.
29

What is a traceability matrix?

AdobeMedium
Save to ▾

A grid mapping requirements to test cases and defects, proving every requirement is tested.
30

What is pairwise testing?

AdobeMedium
Save to ▾

A technique that tests all pairs of input values instead of every combination, greatly reducing test cases while catching most defects.
31

What is the difference between a story, epic, task and bug in JIRA?

AdobeMedium
Save to ▾
Show answer
An epic is a large body of work; stories are user-facing slices of it; tasks are technical work items; bugs are defects.
32

What is CI/CD and how does testing fit?

AdobeMedium
Save to ▾
Show answer
Code is built and tested automatically on each change; tests are quality gates that stop faulty builds from moving forward.

What is error guessing?

AdobeMedium
Save to ▾
Show answer
Using experience to guess where defects likely hide, such as empty fields, special characters or unexpected sequences, and designing tests for them.
36

What is the difference between an error, a defect and a failure?

AdobeEasy
Save to ▾
Show answer
A human error causes a defect in the code, and when that defect is executed it produces a failure visible to users.
37

How would you test a login page for security?

AdobeHard
Save to ▾
Show answer
Check SQL injection, brute-force lockout, password masking, session timeout, HTTPS, cookie flags, error messages not revealing users and password reset flow.
38

What is the use of SQL GROUP BY and HAVING in test validation?

AdobeMedium
Save to ▾
Show answer
They let testers verify totals and counts per category, such as the number of orders per customer, and compare them with the UI or reports.
39

What is the difference between smoke testing in CI and full regression?

AdobeMedium
Save to ▾
Show answer
Smoke tests run on every build for quick feedback; full regression runs less often, such as nightly or before release.
40

What is a bug triage meeting?

AdobeMedium
Save to ▾
Show answer

41

What is TDD vs BDD?

AdobeMedium
Save to ▾
