if, else if, else, comparison operators (==, !=, >, <), logical operators (&&, ||), nested conditions, ternary operator

Day 4 · Loops — for & while

for loop, while loop, do-while, break, continue, nested loops, loop through numbers/strings

Day 5 · Methods

Define methods, parameters & return types, void vs return, method overloading, static keyword, calling methods from main()

Day 6 · Arrays, Lists & Strings

int[], String[], ArrayList, .add(), .get(), .size(), String methods: .length(), .substring(), .contains(), .split(), .equals()

Day 7 · OOP — Classes & Objects

Class, Object, Constructor, this keyword, Getters/Setters, Inheritance (extends), super, Method overriding

Day 8 · Setup Selenium & Launch Chrome

Add Selenium JAR/Maven dependency, ChromeDriver setup, WebDriver driver = new ChromeDriver(), driver.get(), driver.quit()

Day 9 · Find Elements — ID, Name, Class

By.id(), By.name(), By.className(), By.tagName(), By.linkText(), By.partialLinkText(), findElement vs findElements

Day 10 · CSS Selectors

#id, .class, tag[attr='value'], :nth-child(), combinators (>, +, ~), chaining selectors

Day 11 · XPath Basics

Absolute vs relative XPath, //tag[@attr='value'], text(), contains(), starts-with(), axes: parent, following-sibling, ancestor

Day 12 · Click, Type, Read Text

.click(), .sendKeys(), .getText(), .getAttribute(), .isDisplayed(), .isEnabled(), .isSelected(), .clear()

Day 13 · Practice — Forms & Inputs

Text fields, email, password, textarea, submit button, read output, form validation messages

Day 14 · Practice — Dropdowns & Checkboxes

Select class, selectByValue(), selectByVisibleText(), selectByIndex(), checkbox .click(), radio buttons, verify selected state

Day 15 · Alerts

switchTo().alert(), .accept(), .dismiss(), .getText(), .sendKeys(), confirm box, prompt box

Day 16 · iFrames

switchTo().frame(index), switchTo().frame(nameOrId), switchTo().frame(element), switchTo().defaultContent(), nested frames

Day 17 · Windows & Tabs

getWindowHandle(), getWindowHandles(), switchTo().window(), close vs quit, handle new tabs opened by links

Day 18 · Tables

Locate rows with //table//tr, cells with //td, dynamic row count, read cell by row+col index, search table for value

Day 19 · File Upload & Download

Upload: sendKeys(absolutePath) on file input, download: browser profile config, verify file exists on disk

Day 20 · Mouse & Keyboard Actions

Actions class, .moveToElement(), .doubleClick(), .contextClick(), .dragAndDrop(), Keys.ENTER, Keys.TAB, key combos

Day 21 · Review Day

Debug Day 13-20 scripts, fix StaleElementException, NoSuchElementException, ElementNotInteractableException, refactor repeated code

Day 22 · Why Tests Fail

Timing issues, race conditions, Thread.sleep() problems, implicit wait, page load timeout, script timeout

Day 23 · Explicit Wait

WebDriverWait, ExpectedConditions.visibilityOf(), .elementToBeClickable(), .presenceOfElementLocated(), .textToBe(), custom wait conditions

Day 24 · Practice — Waits

Delayed buttons, loading spinners, disappearing elements, progress bars, elements appearing after AJAX calls

Day 25 · Dynamic Content

AJAX calls, content loaded without page refresh, wait for data to render, stalenessOf(), retry patterns

Day 26 · Cookies & Storage

manage().getCookies(), .addCookie(), .deleteCookie(), JavaScript executor for localStorage.getItem(), sessionStorage

Day 27 · Shadow DOM & Date Pickers

shadowRoot, getShadowRoot(), JS executor for shadow DOM, date picker interaction, calendar navigation, sendKeys date format

Day 28 · Real-World Challenges

Dynamic IDs, stale elements, overlapping elements, infinite scroll, lazy loading, hidden elements, auto-complete fields

Day 29 · TestNG Setup

Add TestNG dependency, @Test annotation, run tests, test output, testng.xml suite file, test groups

Day 30 · Assertions & Lifecycle

assertEquals, assertTrue, assertFalse, assertNotNull, @BeforeMethod, @AfterMethod, @BeforeClass, @AfterClass, test execution order

Day 31 · Data-Driven Testing

@DataProvider, return Object[][], parameterized tests, read test data from arrays, multiple login scenarios from one test

Day 32 · Page Object Model — Concept

Why POM, separate test logic from page logic, one class per page, methods return page objects, benefits for maintenance

Day 33 · POM — BasePage & Pages

BasePage: click(), type(), waitForElement(), getText(). LoginPage extends BasePage, @FindBy, PageFactory.initElements()

Day 34 · POM — End-to-End Flow

Chain page objects: Login → Dashboard → Transfer → Verify. Assertions in test class, not page class. Test reads like English

Day 35 · POM Practice — Shopping Portal

Build ShopHomePage, ProductPage, CartPage, CheckoutPage. Write 3 E2E tests using your page objects

Day 36 · Maven

pom.xml structure, groupId, artifactId, <dependencies>, add Selenium + TestNG deps, mvn clean test, Maven lifecycle

Day 37 · Git & GitHub

git init, git add, git commit, git push, .gitignore, create GitHub repo, clone, branches, pull requests basics

Day 38 · E2E — Banking Portal

Day 39 · E2E — PolicyDekho

Calculate premium, apply for policy, upload documents, file a claim. Different domain, same framework pattern

Day 40 · Test Reports — Allure

Add Allure dependency, @Step, @Description, generate HTML report, screenshots on failure, attach logs
