How to Become A Manual Tester Career Guide: Skills, Roles, & Salary

The article covers various aspects of manual testing, providing a comprehensive overview for aspiring testers and professionals. It starts by defining manual testing as the process of manually inspecting software to identify bugs and defects.Manual testing is essential, especially when automation isn't feasible or for tasks like testing complex UIs and dynamic systems.

What is Manual Testing?

Manual testing is the process of testing software manually to identify bugs, issues, and defects in an application. In manual testing, testers interact with the application under test just like an end user would to verify if all the features are working as expected.

Some key characteristics of manual testing are:

  • It is performed manually by human testers without any support from automation tools.
  • It involves executing test cases by providing various inputs and verifying the expected and actual results.
  • It focuses on functional and system testing of the application.
  • Testers need to have expertise in the application domain and type of testing.
  • It is time-consuming and labor-intensive but necessary.

Manual testing is an essential component of the overall software testing process and complements automated testing as well. It is especially useful in:

  • Testing complex UI flows and table structures.
  • Exploratory testing to discover defects.
  • Testing dynamically changing systems.
  • Validation of fixes for detected defects.
  • When automation is not feasible or available.

Types of Manual Testing

There are several types of manual software testing that testers need to be aware of. Here are the major types of manual testing:

  1. Functional Testing
  2. Usability Testing
  3. UI Testing
  4. Integration Testing
  5. Accessibility Testing
  6. Localization Testing
  7. Security Testing
  8. Compatibility Testing
  9. System Testing

Functional Testing

Functional testing evaluates the functionality of an application by testing each functionality and feature against the specified requirements.

Examples of functional testing

  • Checking form validations
  • Testing login and logout
  • Verifying navigation menus and links
  • Testing CRUD operations

Usability Testing

Usability testing evaluates how user-friendly and intuitive the application interface is for users. It focuses on 5 usability factors:

  • Learnability - How easy is it for new users to learn the application?
  • Efficiency - How quickly can tasks be accomplished?
  • Memorability - Is the interface easy to remember even after sometime?
  • Errors - What errors do users encounter and how severe are they?
  • Satisfaction - How pleasant is it to use the application design?

Examples of usability testing

  • Observing users try to accomplish tasks on the interface.
  • Identifying navigation issues.
  • Checking if icons and buttons are intuitive.

UI Testing

UI testing involves testing the graphical user interface of an application. It evaluates if UI elements like menus, buttons, icons, checkboxes follow the specifications and function correctly.

Some examples of UI testing are:

  • Validating alignment, size, and color of UI elements.
  • Testing forms, text boxes, and tabs.
  • Checking that images and icons render correctly.
  • Verifying consistent UI across browsers and devices.

Integration Testing

Integration testing verifies if different modules/components integrate correctly and work as expected.

Examples of Intergration Testing

  • Testing interfaces between components
  • End-to-end testing of workflows
  • Connecting with hardware like printers, networks
  • Testing integration with external systems like payment gateways

Accessibility Testing

Accessibility testing evaluates how accessible the application is for users with disabilities.

Example of Accessibility Testing:

  • Checking if screen reader software can read elements properly
  • Validating keyboard navigation and buttons
  • Testing with sufficient color contrast for color blind users

Localization Testing

Localization testing verifies that the application can be adapted to a specific culture, region, or language.

Example of Localization Testing:

  • Testing for support for different numeric, date, time formats
  • Checking application text and UI elements reflect local culture correctly
  • Verifying currency display and symbols match region
  • Validating translations match the source content

Security Testing

Security testing attempts to identify application vulnerabilities that can lead to security breaches, data leaks, and attacks.

Examples of Security Testing

  • Testing authentication mechanisms like passwords, captcha
  • Checking authorization rules for access to features
  • SQL injection, cross site scripting attacks
  • Validating data encryption for sensitive data
  • Testing that session management and tokens are correctly implemented

Compatibility Testing

This testing evaluates whether the software application runs as intended on different:

  • Browsers - Chrome, Firefox, Safari
  • Operating systems - Windows, Linux, Mac
  • Devices - Desktops, tablets, mobile phones
  • Screen resolutions and sizes

System Testing

System testing tests the end-to-end workflow of an entire system. The scope is from frontend to backend covering all tiers.

Examples of system testing

  • Recovery testing - After failure
  • Load testing - At peak loads
  • Failover testing - On redundant systems
  • Upgrade testing - With new patches/versions
  • Configuration testing - On different environments

This covers the major types of manual testing that testers should be aware of. The key is to identify which types are relevant for your project and focus your efforts there.

When Should You Use Manual Testing?

Despite increasing test automation, there are still many situations where manual testing is advised or may be the only choice:

  • βœ”οΈ New Feature Testing - Any new functionality should be tested manually first before automating to prevent script maintenance overhead.
  • βœ”οΈ Initial Phases Of Testing - Manual exploratory testing helps get an overall perspective before automating end-to-end scenarios.
  • βœ”οΈ UI and Navigation Testing - Automation may not replicate all UI behaviors correctly so manual verification is required.
  • βœ”οΈ Complex Test Scenarios - Test cases with complex conditional logic are challenging to automate compared to manual testing.
  • βœ”οΈ Test Environments Unstable - If test environments change frequently, maintaining automation scripts can be difficult compared to flexible manual testing.
  • βœ”οΈ Agile Projects - With iterative development, it may be preferable to manually test new features added in each sprint rather than continually update automation scripts.
  • βœ”οΈ Small Applications - For apps with few test cases, automation overhead may not justify time required compared to quick manual testing.
  • βœ”οΈ Testing Intermittent Issues - Some bugs are intermittent so manually replicating steps may be required for defects that automation cannot recreate consistently.
  • βœ”οΈ Usability Testing - Real user feedback can only be obtained by manual testing and not automation scripts.
  • βœ”οΈ Resource and Budget Constraints - Automation requires significant initial investment which may not be feasible so manual testing would be the way to go.

Important Manual Testing Concepts

There are some key testing concepts that every tester should be familiar with to excel at manual testing:

1. Test Scenarios vs Test Cases

Test scenarios describe what needs to be tested at a high level. Test cases detail the step by step process to execute the test.

For example, a test scenario would be "Validate password field validations". The test cases would be:

  • Try submitting empty password
  • Input password less than 6 characters
  • Input password more than 12 characters
  • Try special characters in password

2. Positive vs Negative Testing

Positive testing verifies the application works as expected when providing valid inputs and conditions.

Negative testing verifies the application handles invalid data correctly. For example, inputting incorrect password.

3. End-to-End Testing

End-to-end testing mimics a complete user workflow from start to finish through the application. For instance, completing an entire online purchase.

4. Regression Testing

Regression testing verifies existing functionality does not break after new changes or updates to the application.

5. Test Acceptance Criteria

Acceptance criteria specify the requirements that functionality must meet to be accepted and pass the testing.

For example, password field should accept 6 to 12 character passwords.

6. Defect Life Cycle

The defect life cycle consists of the following steps:

  1. Defect Discovery
  2. Defect Logging
  3. Defect Assignment
  4. Defect Resolution
  5. Retesting Resolved Defect
  6. Defect Closure
