TOP 10 ArrayList Methods every SDET should know! ↳ Why ArrayList: ArrayList class uses a dynamic array for storing the elements. It is like an array, but there is no size limit. We can add or remove elements anytime. ↳ Characterstics: 1) The ArrayList in Java can have the duplicate elements also 2) It implements the List interface so we can use all the methods of the List interface here 3) The ArrayList maintains the insertion order internally ↳ Top 10 Methods in ArrayList: 1) add(int index, E element): It is used to insert the specified element at the specified position in a list OR add(E element): This will add element at the last position in list 2) clear(): It is used to remove all of the elements from this list 3) get(int index): It is used to fetch the element from the particular position of the list 4) isEmpty(): It returns true if the list is empty, otherwise false 5) lastIndexOf(Object o): It is used to return the index in this list of the last occurrence of the specified element or -1 if the list does not contain 6) contains(Object o): It returns true if the list contains the specified element otherwise false 7) remove(int index): It is used to remove the element present at the specified position in the list OR remove(Object O): removes the first occurrence of the element present in the list 8) size(): It is used to return the number of elements present in the list 9) removeRange(int fromIndex, int toIndex): It is used to remove all the elements lies within the given range 10) indexOf(Object o)It is used to return the index in this list of the first occurrence of the specified element or -1 if the List does not contain -x-x-x- ↳ Become SDET & Future SDET Manager + 950+ Q&A Bank: https://lnkd.in/gusymgFi ↳ Get your ATS friendly Resume copy, using my latest & update Resume: https://lnkd.in/g9697hy6 #japneetsachdeva

What kind of APIs can you explore & understand before getting into SDET interviews? 1) Web APIs: These are used to enable communication between web servers and clients. For instance, the Twitter API allows developers to access and interact with Twitter's features, such as retrieving tweets or posting new ones. 2) Operating System APIs: These provide an interface for applications to interact with the underlying operating system. The Windows API, for instance, allows software to access various functionalities of the Windows operating system, like creating windows, managing files, and controlling hardware devices 3) Database APIs: These allow applications to communicate with databases. The Java Database Connectivity (JDBC) API enables Java applications to interact with various databases using a standardized interface. 4) Library APIs: Programming libraries often come with APIs that provide predefined functions and classes. The Python Standard Library, for example, offers various modules with APIs for tasks like file handling, networking, and data manipulation. 5) Remote APIs: These enable remote control of devices or services. The remote API of a smart home system might allow a mobile app to control lights, thermostats, and security cameras from a distance. 6)Third-Party APIs: Many companies offer APIs to allow developers to integrate their services into other applications. The Google Maps API lets developers embed interactive maps into their websites or apps. -x-x- Learn & Use GEN AI, API Testing, Automation & more using an updated course for SDETs: https://lnkd.in/gusymgFi Test Automation Engineer Quiz, Exp: 3 to 8 yrs: https://lnkd.in/gHTH3K_g #japneetsachdeva

Top 5 ways to setup Test Data in your Automation Frameworks for SDETs 1) Hard coded data (if data instance is very small) 2) Setup of Excel or CSV files for storing data (Obsolete) 3) Setup of JSON files (Modern) 4) Mocking data using API (Modern) 5 Database integration (Obsolete) Now let's dive into basic setup for each type: 1) Hard Coded: Entering test data directly into our Test Scripts or deriving it through some other function. But its coded directly within our files. Ex: driver.findElement(By.id("username")).sendKeys("testUser"); 2) Using Excel or CSV files: Read test data from CSV or Excel files using libraries like Apache POI or OpenCSV Ex: List<Object[]> data = new ArrayList<>(); String csvFile = "path/to/data.csv"; try (BufferedReader br = new BufferedReader(new FileReader(csvFile))) { String line; while ((line = br.readLine()) != null) { data.add(line.split(",")); } } catch (IOException e) { e.printStackTrace(); } return data.toArray(new Object[0][]); } 3) JSON files: Reading test data using JSON files, use libraries like Jackson, GSON etc. Ex: (Used Jackson) ObjectMapper objectMapper = new ObjectMapper(); try { User user = objectMapper.readValue(new File("path/to/user.json"), User.class); System.out.println(user.getUsername()); System.out.println(user.getPassword()); } catch (IOException e) { e.printStackTrace(); } } 4) Using APIs: Retrieving test data via APIs allows for dynamic and up-to-date test scenarios, particularly useful when dealing with databases Now in this we can use OKHTTP or Rest Assured as per your requirements. As this is little complex to implement as we need to data driver class for APIs & then use it in our Test Classes. I am providing example here: https://shorturl.at/HIGP2 5) Fetching data directly using Database: Useful when data connection is available locally or is not env. dependent. This is usually used in legacy frameworks now, as most of us have migrated to use APIs now. Ex: List<Object[]> data = new ArrayList<>(); String url = "jdbc:mysql://localhost:3306/testdb"; String user = "testuser"; String password = "testpassword"; try (Connection conn = DriverManager.getConnection(url, user, password); Statement stmt = conn.createStatement(); ResultSet rs = stmt.executeQuery("SELECT username, password FROM users")) { while (rs.next()) { data.add(new Object[]{rs.getString("username"), rs.getString("password")}); } } catch (SQLException e) { e.printStackTrace(); } return data.toArray(new Object[0][]); } ⭐ Found this useful?

Business analysts are the unsung heroes of BDD. Here’s why: 🔵 Bridging Gaps: Business analysts (BAs) turn business requirements into precise scenarios, connecting the dots between technical teams and stakeholders. 🔵 Promoting Collaboration: BAs ensure seamless communication between developers, testers, and business stakeholders. 🔵 Defining Requirements: They create crystal-clear scenarios that anticipate every outcome. 🔵 Continuous Improvement: BAs gather feedback and refine requirements iteratively. 🔵 Ensuring Value: They zero in on features that deliver the most business value. In BDD, BAs champion alignment and clarity. The result? Better software quality, enhanced communication, and solutions that truly meet business needs. Got insights on BAs in BDD? Share your thoughts below! 👇 #BDD #BusinessAnalysts #SoftwareDevelopment #ConformIQ

Most people make a common mistake in implementing Page Object Model POM has a basic difference in structure and functionality. As an SDET you should know the benefits for both of them and use it appropriately. In my latest Medium blog, I have clearly stated the differences and advantages, refer here: https://lnkd.in/gUD2YwHa P.S: Do you use structural or functional POM? #japneetsachdeva

Breaking down BDD for Test Automation Engineers & SDET's BDD is a software development approach that promotes collaboration among developers, testers, and non-technical stakeholders in the software development process. BDD means Behavior Driven Development 🌟 ❓ ❓ What are different files used in BDD approach? ❓ ❓ 1) Feature Files: Extension: .feature Purpose: Feature files are written in a natural language format using the Gherkin syntax. They describe the intended behavior of a software feature from the end user's perspective 2) Step Definition Files: Extension: Varies based on the programming language (e.g., .java, .js, .py). Purpose: Step definition files contain the executable code that maps to the steps defined in the feature files 3) Runner Files: Extension: Varies based on the programming language (e.g., .java, .js, .py). Purpose: Runner files are used to configure and execute the tests 4) Configuration Files: Examples: cucumber.yml, behave.ini, etc. Purpose: Configuration files are used to set up and configure the BDD framework. They may include settings related to output formats, parallel execution etc. 5) Hooks Files: Extension: Varies based on the programming language (e.g., .java, .js, .py). Purpose: Hooks files contain code that is executed at specific points during the test execution lifecycle. Hooks are often used for setup and teardown task 6) Test Data Files: Examples: Can be .json, .xlsx, .csv etc. as per the requirement or developers. ❓ ❓ Implementing BDD approach in different Programming Languages: Cucumber: A widely used BDD tool that supports multiple programming languages such as Java, Ruby, and JavaScript. Cucumber helps in writing feature files, and its step definitions can be implemented in the desired programming language. SpecFlow: A BDD framework for .NET, compatible with languages like C# and VB.NET. Behave (Python): A BDD framework for Python applications Collaboration is key for BDD success ⁉ BDD encourages collaboration between team members. Non-technical stakeholders can contribute to feature files, and developers/testers can work together to refine scenarios and step definitions.

Many testers who work as contractors/consultants in product-based companies will face a different set of challenges. Predominantly, the reporting manager's primary focus is on getting the work done and not showing much interest in how you grow as testers. As consultants, the expectations differ as the parent companies generally charge high. As testers, this could be an opportunity that can be utilized to accelerate career growth. As testers, I think, we need to have strategies to deal with escalations. Having a supportive team member and manager does not make you feel lonely during that time. I was working with this engineering manager. He was jovial and fun to work with. Humble, easy to approach. He used to sit on the floor if the meeting room was full. The whole floor would know when he was attending an IPL match. (He had a good collection of toy cars on his desk!). This happened when I was 1 year+ experience in R&D where I worked as a contractor. One morning, I turned on my PC and was about to check my emails. My manager came to my desk. Our conversations: Manager: Shubha don't read the emails.  Me: Why? Anything that you want to share? Is it regarding the severity 1 issue that I raised yesterday?  Manager: Yes. Don't get scared looking at emails. As we are nearing release, finding a severity 1 issue will send panic attacks across the teams.  When the outlook opened, I saw an avalanche of emails.  The manager was sitting next to me and taking the keyboard started drafting an email.  He asked me to read it once and send the email. Later we went for a coffee and a hearty laugh. The manager could have escalated to my parent company and I would have had a tough time dealing with it. Instead, he taught me how to de-escalate the tense situation through his actions. My takeaways: 1. Do not press the panic buttons in the time of crisis. Especially when there is an escalation.  2. Take deep breaths and go step by step. Keeping calm will help to be logical and solve the problem.  3. Go with facts. Ask for help from seniors if possible.  4. Once the problem is solved, do not forget to add the lesson learned to your journal. So that, you don't repeat the same mistake.  0. Having coffee always works :)  I am curious to know your stories, where earlier in your career how did you deal with escalations. #softwaretesting #learning #customers #marketing #escalations ******************************************************************************** (3/50)~ 15Nov2024 ~I am writing 50 posts about testing for 50 days.

Frequently asked API Testing Interview Questions What is Rest API? REST API, or Representational State Transfer, is a design approach that operates on a client-server model where client apps initiate a request to view or edit server info. Each request to a RESTful API is autonomous. This means that every request needs to have all the requisite info for the server to grasp and address that request. Resources are the underlying content presented by the API, which are distinguished by their URIs, or Uniform Resource Identifiers. Standard HTTP modes are the primary method of doing operations on resources in RESTful APIs: - GET, which retrieves data - POST, which makes new data - PUT, to adjust current data and DELETE, getting rid of the data. Data entities are typically illustrated in two accessible formats, JSON or JavaScript Object Notation, and XML, the extensible Markup Language. The required data to manage the client's installment has to be available in each appeal from the client to the server. In-between requests, the server does not sustain any status from the clents. The uniform interface is a key feature of REST API, that simplifies the connection between client and server. Therefore it makes concerted use of standard HTTP modes, resources URIs along with their response calendars. Use below PDF, to refer some important Q&A to prepare before interviews. Note: Q&A should only be referred, once you learned and implemented these in your projects or work. -x-x- To get more such SDET Interview Questions & Answers, refer: https://lnkd.in/gSU-m2F7 API Test Automation using RestAssured & JAVA with Framework Creation from Scratch: https://lnkd.in/g8qgu-Qz #japneetsachdeva
