01
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.
02
What do HTTP status codes 200, 201, 400, 401, 403, 404 and 500 mean?
Situation: our developers were in another time zone and test failures waited a day for replies. Task: reduce delays. Action: I wrote clear failure reports with screenshots, logs and steps, recorded short videos for complex issues, and set a fixed 30-minute overlap call twice a week. Result: turnaround on defects dropped from two days to about one, and fewer issues bounced back.
06
Your company is debating a cloud device farm versus an in-house device lab. How do you advise?
A cloud farm gives hundreds of device and OS combinations, parallel capacity and no hardware maintenance, but costs per minute, adds network latency and may raise data privacy concerns. An in-house lab is cheaper over time for a small fixed set of devices and gives full control, but needs USB hubs, OS updates, battery care and someone to maintain it. Many teams keep a few local devices for debugging and use the cloud for wide coverage.
07
How have you handled disagreement with a developer about whether something is a bug?
Situation: a developer said a rounding difference in invoice totals was expected. Task: resolve it without friction. Action: I checked the requirement, found it specified rounding per line, and brought the document and a test case with expected values to a quick call with the BA. Result: the BA confirmed it was a bug, it was fixed, and we added the rule to the acceptance criteria.
final makes a variable, method or class unchangeable; finally is a block that always runs after try-catch; finalize is a deprecated method called before garbage collection.
09
Write a REST Assured test using RequestSpecBuilder and ResponseSpecBuilder.
Low-end devices are slower, so fixed waits and short timeouts expire before screens render. Replace sleeps with explicit waits and increase timeouts sensibly. Check for vendor-specific pop-ups, battery optimisation dialogs or different keyboards on that brand. Compare screen size and resolution, since coordinate-based taps break. Collect device logs with adb logcat and screen recordings to see what the app was doing. Also check whether the app crashed due to low memory.
11
Should page objects use inheritance or composition?
Use a shallow inheritance only for a BasePage with common helpers. For shared UI parts, use composition: a page has a Header, a SideMenu and a Table component. Deep inheritance like BasePage to ListPage to ProductListPage to SaleProductListPage becomes fragile and hard to debug. Composition mirrors how modern UIs are built from components and keeps classes small.
Optional is a container that may or may not hold a value, introduced in Java 8 to avoid returning null. In test code it suits lookups that can legitimately find nothing, such as finding a row in a table or reading an optional config key. Callers use orElse, orElseThrow or ifPresent instead of null checks. For example, findRowByName(name).orElseThrow(() -> new AssertionError(name + " not found")) gives a clear failure message.
16
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.
17
Which locator strategies does Appium support and which should you prefer?
Appium supports accessibility id, id (resource-id on Android), class name, XPath, Android UiAutomator selectors, iOS predicate strings and iOS class chains. Prefer accessibility id because it is fast, works across Android and iOS and also improves app accessibility. Next use resource-id or iOS predicates. Use XPath only as a last resort because it walks the whole UI tree and is slow and brittle, especially on iOS.
18
What are page components or page fragments in POM?
Components are classes for UI parts that repeat across pages, such as the header, search bar, date picker or a data table. A page object then has-a component: homePage.header().search("laptop"). This follows composition over inheritance, avoids duplicate locators and matches modern component-based frontends. Components are usually scoped to a root WebElement so locators search only inside that element.
19
How do you handle a test that is flaky only in headless mode?
Run JMeter in non-GUI mode in a pipeline stage, ideally inside a Docker image with a pinned JMeter version, and archive the JTL and HTML report. Enforce SLAs with Duration Assertions or a JSR223 check, or parse the JTL in a script that compares 95th percentile and error rate with thresholds and exits non-zero. The Jenkins Performance plugin can also mark builds unstable or failed based on thresholds and trends.
Check CPU and memory usage of application servers, garbage collection pauses and heap usage for Java services, thread pool and connection pool saturation, database slow queries, locks and connection counts, disk I/O and network bandwidth. Also look at load balancer and cache hit rates and error logs. Correlate the timestamp of the slowdown with these graphs in an APM or monitoring tool to find which resource saturated first.
24
An element is visible in Appium Inspector but your test throws NoSuchElementException on the device. What do you check?
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.
25
Tell me about a time your API tests caught a breaking change before the UI tests did.
Situation: a backend team renamed a response field during a refactor. Task: our nightly REST Assured suite had to protect the mobile and web clients. Action: schema validation failed within minutes of the merge, and I shared the failing response and the contract with the developer. Result: the field was restored with a deprecation plan before the UI suite even ran, and the team added our schema tests to their pull request checks.
26
What is the Transaction Controller in JMeter used for?
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.
Re-locate the element after the DOM refreshes, use explicit waits for the refreshed element, don't keep element references for long, or wrap the action in retry logic.
A special method that initialises an object. It can be overloaded with different parameters, and testers use it to pass the WebDriver into page classes.
29
How do you mock an external API in automation tests?
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.
30
What is polymorphism and how does it show up in Selenium?
Inside a <test>, add <groups><run><include name="smoke"/><exclude name="broken"/></run></groups>. Only methods in the included groups run, minus excluded ones. Configuration methods must have alwaysRun = true or belong to the groups, or they will be skipped. You can also pass -Dgroups=smoke from Maven Surefire for CI selection.
Hooks are Java methods annotated with @Before, @After, @BeforeStep and @AfterStep that run around scenarios or steps. Background is visible in the feature file and describes business preconditions; hooks are hidden technical setup such as starting the browser, cleaning data or attaching screenshots. Hooks can be ordered with the order attribute and filtered by tag expressions, for example @Before("@ui").
34
What is the LoadableComponent pattern in Selenium?
LoadableComponent is a Selenium support class that standardises how a page object ensures it is loaded. You extend it and implement load(), which navigates to the page, and isLoaded(), which throws an Error if the page is not ready. Calling get() checks isLoaded and calls load only if needed, then checks again. It gives a consistent, self-verifying way to open pages and fails fast with a clear message.
35
Why do Selenium browser containers need a larger shm_size?
Chrome and Firefox use shared memory at /dev/shm for rendering and inter-process communication. Docker gives containers only 64 MB of shared memory by default, which is not enough for modern pages, so the browser tab crashes with errors like session deleted because of page crash. Setting shm_size to 2g in Compose, or --shm-size=2g with docker run, fixes it. Mounting /dev/shm from the host is an alternative.
