01
Write Selenium code to verify that all links on a page are not broken.
appPackage is the unique application id of an Android app, such as com.example.shop, and appActivity is the activity screen that Appium launches first, such as .MainActivity. Together they let Appium start an app that is already installed without passing the apk path. You can find them with adb shell dumpsys window or by reading the manifest. A wrong activity name is a common reason a session fails to start.
Use a tool such as WireMock or MockServer to run a stub server that returns predefined responses for given requests. Point the application or tests to the stub with configuration. This lets you test error codes, timeouts and edge cases that are hard to trigger on the real service, and keeps tests stable when the third party is down. Still keep a few tests against the real integration.
06
Tests run fine on Chrome but fail on Firefox at the same step. How do you investigate?
Rerun on Firefox with screenshots and logs. Common causes are timing differences, different default window sizes, unsupported CSS or JavaScript behaviour, alerts handled differently, or a driver version mismatch. Compare the DOM in both browsers at that step. Fix by using explicit waits, setting window size, and reporting genuine browser bugs to developers.
07
Tests running inside Docker cannot reach the application running on the host's localhost. Why, and how do you fix it?
Inside a container, localhost means the container itself, not the host machine. On Docker Desktop use host.docker.internal as the host name. On Linux add extra_hosts with host.docker.internal:host-gateway, or use the host's IP. A cleaner option is running the application in the same Compose network and calling it by its service name, such as http://web:8080. Make sure the app listens on 0.0.0.0, not only 127.0.0.1.
Common triggers are webhooks from GitHub, GitLab or Bitbucket on push or pull request, cron schedules with triggers { cron('H 2 * * *') } for nightly regression, polling SCM (less efficient), and upstream jobs completing, such as running tests after a deploy job. Multibranch pipelines automatically create jobs for each branch and pull request containing a Jenkinsfile.
09
What are the advantages of version control for test code?
Profiles are sets of configuration activated by name, such as -Pqa or -Pstaging, or by conditions. In automation they switch environment URLs, suite files, browsers or parallel settings without changing code. For example a regression profile sets suiteXml to regression.xml and threadCount to 4. Combined with properties files, profiles keep one codebase for every environment.
11
What is the difference between a Docker image and a container?
An image is a read-only template that contains an operating system layer, software and configuration, for example selenium/standalone-chrome with Chrome and ChromeDriver installed. A container is a running instance of an image with its own process, network and writable layer. You can start many containers from one image and destroy them after a test run. This is why every run starts from the same clean browser environment.
12
How do you avoid page object classes becoming too large?
Split pages into components for repeated or complex areas, keep only user actions as public methods, move generic helpers to BasePage or utilities, and avoid one method per element. If a page has distinct modes like view and edit, use separate classes. Review page classes during code review and refactor when they cross a few hundred lines.
13
What are the UiAutomator2 and XCUITest drivers in Appium?
They are the platform drivers that actually control the device. UiAutomator2 drives Android by installing a small server app on the device that uses Google's UiAutomator framework. XCUITest drives iOS through Apple's XCTest framework via WebDriverAgent, which needs Xcode and signing for real devices. In Appium 2 they are installed separately with appium driver install, so each project picks only the drivers and versions it needs.
14
What is the difference between continuous delivery and continuous deployment?
In continuous delivery every change that passes the pipeline is ready to release, but a person approves the production deployment. In continuous deployment every passing change is released to production automatically. Continuous deployment requires very reliable automated tests and monitoring, because there is no manual check before users see the change.
15
How do you test an API that supports multiple versions at the same time?
First learn how versions are selected: URL path like /v1 and /v2, a header, or a query parameter. Keep a request specification per version and run the shared contract tests against each supported version, plus version-specific tests for new fields or changed behaviour. Check that old versions still return their original response shape so existing clients do not break, and that deprecated versions send the agreed deprecation headers or errors.
First check timing: the screen may still be loading, so add an explicit wait for presence. Then check context: in a hybrid app the element may be in a webview while you are in NATIVE_APP. Confirm the locator matches exactly, including package prefix in resource-id. The element may be off screen in a list, so scroll first. Also check that the Inspector session used the same app build, language and device size as the test.
19
What is polymorphism and how does it show up in Selenium?
Situation: during a sprint, my nightly regression showed checkout failing only for one payment option. Task: confirm if it was a test issue or a real bug. Action: I reproduced it manually, checked the API response and found a wrong tax value, then logged a clear defect with steps, logs and screenshots. Result: developers fixed it before the release and the test was added to the smoke suite.
21
A teammate compares two strings with == and the test sometimes passes and sometimes fails. Explain.
== compares object references, not content. String literals are interned, so two literals with the same text may share a reference and == returns true, but strings read from the UI or built at runtime are new objects, so == returns false even with the same text. Use equals() or equalsIgnoreCase() for content, and Objects.equals() to be null-safe.
A Transaction Controller groups several samplers into one logical business transaction, such as Login, which may include loading the page, posting credentials and fetching the dashboard. JMeter reports an extra sample with the total time of the group, so reports show user-level timings instead of only individual requests. With generate parent sample enabled the children appear nested. It makes SLA reporting easier for business stakeholders.
24
What is a smoke test versus a sanity test in a pipeline?
A smoke test is a broad, shallow check that the build is stable enough for further testing, such as the app launches, login works and main pages load. A sanity test is a narrow check after a specific fix or change to confirm it works. In pipelines, smoke runs on every deploy as a gate; sanity checks are targeted runs for a particular change.
Configure plugins such as pretty for console, html:target/cucumber.html for a built-in report and json:target/cucumber.json for tools. The JSON feeds maven-cucumber-reporting or the Jenkins Cucumber Reports plugin. For richer dashboards, add the Allure or Extent Cucumber adapter. Attach screenshots and logs in hooks so failures can be analysed from the report alone.
Docker Compose lets you define several containers, their images, ports, environment variables and networks in one docker-compose.yml file and start them together with docker compose up. For Selenium it means a hub plus Chrome, Firefox and Edge nodes, and even the application under test, start with one command on any laptop or CI agent. The file is version-controlled, so every tester and pipeline uses the same Grid setup.
28
How do you run Selenium tests in Docker containers in CI?
Use official Selenium images, either standalone-chrome for simple runs or a Grid with hub and node containers via Docker Compose. The test container or Jenkins agent points RemoteWebDriver to http://selenium-hub:4444. Containers give the same browser version everywhere and are cleaned after each run. Add shm_size for Chrome stability and record videos for failed tests if needed.
29
How do you validate response headers and cookies in REST Assured?
Use then().header("Content-Type", containsString("application/json")) and then().cookie("sessionId", notNullValue()). To read values, use response.getHeader("X-Request-Id") or response.getCookie("sessionId"). Header checks matter for caching, security headers like Strict-Transport-Security, and correlation IDs used when debugging failures across services. Also assert that sensitive headers such as server version details are not exposed.
30
What is the difference between == and equals() in Java?
An idempotent operation gives the same result no matter how many times it is called. GET, PUT and DELETE should be idempotent; POST usually is not. Testers verify that repeating a PUT does not create duplicates and that a second DELETE returns a sensible status like 404 or 204. Retries in networks and CI make idempotency important to verify.
GraphQL usually has one endpoint and you send a POST with a query and variables. Tests check the data returned matches the requested fields, that errors appear in the errors array, often with status 200, and that authorization applies per field. Also test query depth limits and nested queries for performance. REST Assured works fine by sending the query as JSON body.
33
How do you test API security basics as an automation tester?
Check that endpoints reject missing or invalid tokens with 401, block users from other users' data with 403 or 404, validate input to prevent injection, do not leak stack traces or sensitive fields, enforce HTTPS and set security headers. Automate these as negative tests in the regression suite and work with the security team for deeper penetration testing.
34
How do you send form parameters and headers in REST Assured?
Use formParam("username", "asha") and formParam("password", "pass") for application/x-www-form-urlencoded bodies; REST Assured sets the content type for you. Add headers with header("X-Client", "web") or headers(map) for many at once. Cookies use cookie(name, value). Keep common headers in a RequestSpecification so individual tests only add what is specific to them.
35
How do you handle a dropdown that is not a <select> tag?
The default lifecycle has phases in order: validate, compile, test, package, verify, install and deploy. Running a phase runs all earlier phases too, so mvn test compiles and then runs unit tests through Surefire. mvn verify also runs integration tests with Failsafe. There are also clean and site lifecycles. Automation suites usually run with mvn clean test or mvn clean verify.
Overloading: same method name, different parameters, in the same class (compile time). Overriding: a subclass redefines a parent method with the same signature (runtime polymorphism). WebDriver driver = new ChromeDriver() is runtime polymorphism.
38
What are TestNG and JUnit 5 differences that matter in automation?
TestNG has built-in groups, dependencies, suite XML, DataProvider and flexible parallel options, which suit large Selenium suites. JUnit 5 has a modular platform, tags, parameterized tests, extensions and strong IDE and tool support, and is the default for Spring and Cucumber's JUnit Platform engine. Both are capable; the choice usually follows team standards and existing frameworks.
39
How would you explain to a manager why mobile automation estimates are higher than web estimates?
Situation: a manager questioned why my mobile estimate was nearly double the web one. Task: justify it with facts. Action: I listed the extra work: two platforms with separate locators, device and OS version matrix, slower sessions, app builds and signing, gestures and permissions, and device lab maintenance. I showed timings from a pilot of five tests. Result: the manager accepted a phased plan starting with Android smoke tests, and later estimates were trusted because they were data-backed.
Encapsulation: private locators with public page methods. Inheritance: pages extend a BasePage. Polymorphism: the WebDriver interface for different browsers. Abstraction: utility layers hiding Selenium details.
