How to input value into an international number text box in selenium

Below is the text box and the corresponding HTML:

If I used sendkeys, sometimes it may not working

driver.findElement(By.name(“mainphone”)).sendKeys(“(02)2222-2222”);
driver.findElement(By.id(“mobilephone”)).sendKeys(“05-5555-5555”);

If sendkeys() methods are not working then use following two ways to input text:

Before sendkeys() use click() method to click inside textfield i.e:

driver.findElement(By.name("mainphone")).click();
driver.findElement(By.name("mainphone")).sendKeys("(02)2222-2222");   
driver.findElement(By.id("mobilephone")).click();
driver.findElement(By.id("mobilephone")).sendKeys("05-5555-5555");

Technical & Soft Skills Every QA Tester Should Master

🧠 Top Skills That Are Important for a Test Professional in 2025

Software testing has transformed rapidly with the rise of automation, agile, AI, and complex digital ecosystems. A test professional today is no longer limited to clicking through test cases—they are expected to be problem solvers, communicators, coders, and sometimes even data analysts.

The infographic below shows a breakdown of the most critical testing skills, based on industry-wide feedback.

📌 Why These Skills Matter

With constant software releases, test professionals need to ensure quality without slowing down development. That means:

  • Faster feedback loops
  • Deeper collaboration with developers
  • Testing beyond just functionality (security, usability, performance)
  • Understanding user behavior and business context

These skills help testers not just find bugs—but prevent them.

📊 Top Skills Breakdown

Here’s a detailed look at what each skill means and why it matters:

1. 🗣️ Communication Skills (75% Very Important)

📍 Why it’s critical:
Testers must clearly document bugs, write test cases, and explain defects to developers and stakeholders. Good communication prevents misunderstandings and keeps the team aligned.

2. ⚙️ Automation & Scripting (65%)

📍 Why it’s critical:
Manual testing can’t scale. Knowledge of automation frameworks like Selenium, Cypress, or Playwright is essential. Scripting in languages like Python, Java, or JavaScript can save hours of repetitive work.

3. 📚 General Testing Methodologies (62%)

📍 Why it’s critical:
Understanding black-box, white-box, regression, smoke, and exploratory testing helps testers select the right test at the right time.

4. 🌐 Web Technologies (60%)

📍 Why it’s critical:
Modern testers must understand HTML, CSS, and JavaScript to validate front-end issues or debug problems in browser-based apps.

5. 🔌 API Testing (55%)

📍 Why it’s critical:
More apps rely on microservices and APIs. Testers need tools like Postman, REST Assured, or Karate to test APIs for performance, reliability, and correctness.

6. 🛡️ Security Testing (48%)

📍 Why it’s critical:
Testers play a role in identifying vulnerabilities—such as XSS, injection attacks, or broken authentication—before attackers do.

7. 🔁 Agile Methodologies (45%)

📍 Why it’s critical:
Testers in Agile teams need to test early and often, work in sprints, and use practices like TDD (Test-Driven Development) and CI/CD pipelines.

8. 📈 Performance & Load Testing (42%)

📍 Why it’s critical:
Users expect fast apps. Testers use tools like JMeter, Gatling, or k6 to simulate thousands of users and ensure the app can handle peak loads.

9. 📱 Mobile Technologies (39%)

📍 Why it’s critical:
Testing on Android and iOS requires mobile-specific knowledge (e.g., gestures, screen sizes, emulators, Appium automation).

10. 🧠 Customer-Facing & Business Skills

📍 Why it’s critical:
Testers with empathy and business understanding catch real-world bugs—issues a user would actually care about.

🧩 Other Valuable (Emerging) Skills:

SkillUse Case
Data AnalysisUnderstanding logs, charts, trends for performance and issue tracking
Cloud TestingTesting apps deployed in AWS, Azure, GCP

  2. 📚 Read about new tools and trends in QA weekly
  3. 🧪 Participate in real-world testing challenges (e.g., Bug Bashes, uTest)
  4. 🤝 Collaborate with developers and product owners
  5. 📊 Learn to report insights, not just bugs

IoT Testing Explained: A Complete Guide for QA Engineers

IoT Testing (Internet of Things Testing) is the process of testing the functionality, security, performance, and compatibility of IoT devices and systems. As more smart devices get connected—like smartwatches, home sensors, connected cars, and industrial machines—IoT Testing ensures everything works smoothly and safely.

When IoT devices fail, it can lead to real-world problems like security breaches, system crashes, or poor customer experiences. That’s why proper testing is critical before launching any IoT product.

🔍 Why is IoT Testing Important?

Imagine a smart home system where the thermostat, security cameras, and lights are all connected. If even one device malfunctions, the whole system could fail. IoT Testing helps developers find and fix issues before they reach real users.

🧰 Types of IoT Testing (Explained Simply)

Here are the main types of IoT Testing you should know:

1. ✅ Usability Testing

What it does:
Checks if the IoT device is easy to use.
Example: Is the mobile app for a smart bulb simple to navigate?

2. 🧩 Compatibility Testing

What it does:
Makes sure the device works across different networks, platforms, and versions.
Example: Can a smart fridge connect with both Android and iOS apps?

3. ⚙️ Reliability & Scalability Testing

What it does:
Tests how stable the system is when more devices or users are added.
Example: Will a smart sensor network still work if 100 more sensors are added?

4. 🔐 Security Testing

What it does:
Validates if the system is safe from hackers and protects user data.
Example: Can unauthorized users access your smart door lock?

5. 📈 Performance Testing

What it does:
Checks how fast and responsive the devices are.
Example: Does the smart thermostat respond quickly when you change the temperature?

6. 📊 Data Integrity Testing

What it does:
Makes sure the data sent between devices is correct and uncorrupted.
Example: If a heart monitor sends data to a doctor’s dashboard, is that data accurate?

🚀 Final Thoughts

IoT Testing ensures that smart devices are reliable, secure, and user-friendly before reaching the market. It helps avoid costly failures and builds trust with users. Whether you’re testing a smart appliance, industrial sensor, or wearable device—these testing types are essential for success in the IoT world.
