Mobile Application Testing Basics: Manual vs Automated…

In the dynamic landscape of mobile app development, thorough testing stands as a cornerstone to guarantee a flawless user experience. The testing arena can be divided into two primary methodologies: Manual Testing and Automated Testing. Let’s delve deeper into the fundamentals of these approaches:

Manual Testing

Manual testing is a hands-on process where human testers meticulously navigate through an app’s various features, interfaces, and functionalities. It involves simulating real-world user interactions to uncover issues such as user interface glitches, usability concerns, and discrepancies across different devices. Despite being time-intensive and relying on human effort, manual testing excels in its capacity to identify subjective problems that automated scripts might overlook. This approach is particularly valuable during the early stages of development and in situations where a personal touch is essential.

Automated Testing

Automated testing, on the other hand, relies on scripts and specialized tools to execute predefined test cases. These scripts mimic user actions and systematically run through predetermined test scenarios. Automated testing proves highly effective for repetitive tasks, regression testing, and performance evaluations. It offers swift feedback during the development phase, accelerates testing cycles, and guarantees consistency in test execution. However, it’s important to note that automated testing cannot completely replace human intuition, especially when assessing subjective aspects of the app.

Manual Testing vs. Automated Testing

• Manual Testing

  • Pros: Deep understanding of user behavior, thorough exploratory testing, detection of subjective issues.
  • Cons: Time-consuming, resource-intensive, challenging to reproduce precise steps.

• Automated Testing

  • Pros: Efficiency, repeatability, scalability, suitability for regression testing.
  • Cons: Initial setup effort, inability to detect subtle UI/UX issues, inability to replicate human creativity.

Cost of Manual Testing

Manual testing incurs costs related to the workforce needed to perform testing. As human testers are involved, expenses can escalate with the size of the testing team and the duration of testing cycles. Additionally, manual testing’s iterative nature might lead to increased expenses over time, especially during regression testing phases.

Cost of Automated Testing

While automated testing requires initial investment in setting up the testing framework and developing scripts, it can yield long-term cost savings. Automated tests can be run repeatedly without additional labor costs. However, maintenance costs might arise as the app evolves, requiring adjustments to the scripts. Additionally, acquiring and maintaining the necessary automation tools and infrastructure contributes to the overall cost.

Tools Available in Automation Testing

Several automation testing tools can streamline the process and enhance efficiency:

• Appium: An open-source tool for automating native, mobile web, and hybrid applications on iOS and Android platforms.
• Calabash: A cross-platform automation tool that supports both Android and iOS native apps.
• XCTest and UI Automator: Native automation frameworks for iOS and Android, respectively.
• Selenium: Widely used for web automation, Selenium can also be extended to automate mobile browsers.
• Robot Framework: A generic automation framework that can be used for both web and mobile applications.
• Espresso: A testing framework specifically designed for Android app testing.

Tools and Practices in Manual Testing

Manual testing relies on human skills and judgment, but tools can enhance the process:

• TestRail: A test case management tool that helps organize and track manual test cases.
• JIRA: A popular project management tool that can be used to manage and track manual testing tasks.
• Exploratory Testing: A technique where testers use their intuition and creativity to uncover issues without predefined scripts.
• Usability Testing: Involves real users trying out the app to identify user experience issues.

In conclusion, comprehending the nuances between manual and automated testing is pivotal for successful mobile app development. While each approach possesses its strengths and limitations, combining them strategically can create a comprehensive testing framework that elevates the overall quality of the application. Considering the costs associated with both manual and automated testing aids in making informed decisions that align with project goals and constraints. Additionally, utilizing appropriate testing tools empowers testing teams to work effectively and efficiently.
