01
Write a TestNG listener that logs test start and failure.
Write a utility that reads the sheet with Apache POI and returns Object[][] with one row per test case. Create a @DataProvider method that calls the utility, and set dataProvider = "loginData" on the test. Each row runs as a separate test with its own result. Keep the file in src/test/resources and consider CSV or JSON, which are easier to review in Git.
04
Write an XPath for a button with the text "Login".
Average is the sum divided by count, so a few very slow requests can distort it. Median is the middle value, meaning half the requests were faster. The 95th percentile means 95 percent of requests were faster than that value, which reflects what most users experience including slow cases. SLAs are usually written on 90th, 95th or 99th percentiles because averages hide long tails that frustrate real users.
08
Your UI regression suite has 15 percent flaky failures. How would you bring it under control?
Measure flakiness per test over many runs and fix the worst first. Typical fixes are replacing sleeps with explicit waits, creating independent test data via API, avoiding shared logins, using stable locators, isolating parallel drivers and stubbing unstable third parties. Quarantine known flaky tests into a separate job so they do not block releases, and set a target like under 2 percent.
09
What are Java collections and which ones do testers use most?
ArrayList and LinkedList for lists, HashSet for unique values, HashMap for key-value test data, and Iterator for traversing them, for example collecting web elements in a list.
10
How do you switch between native and webview contexts in a hybrid app?
// Requires the webview to be debuggable in the app build
Set<String> contexts = driver.getContextHandles();
for (String ctx : contexts) {
if (ctx.startsWith("WEBVIEW")) {
driver.context(ctx);
break;
}
}
driver.findElement(By.cssSelector("#email")).sendKeys("qa@test.com");
// back to native controls
driver.context("NATIVE_APP");
Lambdas are short anonymous functions; streams process collections declaratively with filter, map and collect, for example filtering link text from a list of elements.
git cherry-pick <commit> applies the changes of one specific commit onto your current branch, creating a new commit. It is useful when a fix on one branch, such as a locator fix on develop, is urgently needed on a release branch without merging everything else. Overuse creates duplicate commits and confusing history, so prefer normal merges when possible.
13
How do you build dynamic JSON request bodies without hard-coded strings?
Use POJOs with a builder pattern or Lombok @Builder, so tests write User.builder().name("Ravi").role("QA").build(). For quick cases use a HashMap or Jackson ObjectNode. For large templates, keep a JSON file and change fields with a JSON library. Combine with a faker library for unique values. This avoids escaping issues and makes changes to the schema easy to update.
14
How do you handle dynamic elements whose ids change?
ITestContext represents one test tag from testng.xml and is passed to listeners and configuration methods. It holds the suite, included methods and results, and has setAttribute and getAttribute to share values, such as an auth token created in @BeforeTest and read by later classes. Because it is shared by every thread in that test tag, store only thread-safe or read-only data there, not WebDriver instances during parallel runs.
16
How do you create a custom parameter type in Cucumber?
Annotate a method with @ParameterType, giving a regex and returning a domain object. For example @ParameterType("admin|manager|viewer") public Role role(String name) { return Role.valueOf(name.toUpperCase()); } lets you write steps like "I log in as {role}". It keeps conversion logic in one place, makes steps type-safe and gives clearer errors when an invalid value is used.
Continuous Integration builds and tests every commit, and Continuous Delivery ships automatically. Automated tests give fast feedback and gate releases.
Grid 4 is split into the Router, which receives all requests, the Distributor, which assigns new sessions to nodes, the Session Map, which records which node owns each session, the New Session Queue, which holds requests waiting for a free slot, the Event Bus, which lets components communicate, and Nodes, which run the browsers. In standalone or hub mode these run in one process, but they can also be deployed separately to scale.
20
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.
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.
22
During a load test response times rise sharply. Which server-side metrics do you check?
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.
23
What are the advantages of version control for test code?
BasePage is a parent class for all page objects holding common things: the driver reference, a WebDriverWait, and helper methods such as click with wait, type, getText, waitForVisible and scrollIntoView. Child pages extend it and stay focused on page-specific locators and actions. Keep it small; if it grows into hundreds of methods, move helpers into separate utility classes using composition.
25
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.
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.
28
What is the difference between static and non-static members?
Situation: my team needed Android regression tests and I only knew Selenium. Task: deliver a smoke suite in one month. Action: I learned Appium 2 setup, used Appium Inspector to find locators, asked developers to add accessibility ids, and reused our TestNG, POM and reporting structure with a new driver factory. Result: twenty smoke tests ran nightly on emulators within four weeks, and release smoke testing dropped from half a day to forty minutes.
31
An API returns 200 but your REST Assured assertion on a field fails with a null value. How do you debug it?
Log the full response with then().log().all() to see the actual body. Common causes are a wrong JSON path, such as missing a wrapper like data, the field being in an array needing an index, a different content type like XML or HTML error page, or the field name having different case. Fix the path, and add a schema check so structure changes are caught clearly.
Shift-left means testing earlier in the development cycle: reviewing requirements, writing acceptance criteria and test cases before coding, running unit and API tests on every commit, and giving developers fast feedback. Defects found early are cheaper to fix. In practice SDETs pair with developers, add tests to pull request pipelines and test APIs before the UI is built.
33
Your Jenkins test stage marks the build green even though tests failed. Why?
Possibly testFailureIgnore is set to true in Surefire, the shell step uses || true, or the script swallows Maven's exit code. Sometimes tests catch exceptions and never fail. Check the console log for Maven's BUILD result and Surefire summary. Fix the configuration so failures produce a non-zero exit, or use junit publishing to mark the build unstable when tests fail.
34
What is the Optional class in Java and where is it useful in test code?
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.
35
How do you validate a response against a JSON schema in REST Assured?
Add the json-schema-validator dependency, place the schema file in src/test/resources, and assert with then().body(matchesJsonSchemaInClasspath("user-schema.json")). Schema validation checks field types, required fields and structure, so it catches contract changes that value checks might miss. It complements, not replaces, assertions on business values like status or totals.
36
How do you check that the Grid is ready before starting the tests in CI?
Poll the Grid status endpoint, http://hub:4444/status, until the JSON field value.ready is true, which means at least one node has registered. In a shell step you can loop with curl and jq, for example until curl -s http://localhost:4444/status | jq -e '.value.ready'; do sleep 2; done, with an overall timeout. In Compose you can add a healthcheck on the hub. Without this, the first tests fail while nodes are still starting.
