• When designing your application, it’s essential to ensure it performs seamlessly on your target screen resolution. With smartphones and tablets available in a wide range of shapes and sizes, optimizing for different screen resolutions and display densities is critical for delivering a great user experience.

  Here are some commonly used screen resolutions:

  • 320 x 480px
  • 640 x 960px
  • 480 x 800px
  • 720 x 1280px
  • 768 x 1280px
  • 800 x 1280px
  • 1200 x 1920px
  • 2048 x 1536px

  To aid your development process, platforms like Wikipedia offer detailed lists of devices along with their screen resolutions and display densities. Additionally, Google provides valuable insights and statistics on devices with specific screen sizes and densities, helping developers make informed decisions.

  For guidance on how to accommodate multiple screen sizes and resolutions, including pixel density considerations, explore Google’s developer resources. Taking these steps ensures your app looks and performs flawlessly across various devices, enhancing user satisfaction and accessibility.

Grey Box Testing Approach:

• Adopt a grey box testing strategy to examine both the functionality and internal mechanics of the backend, ensuring a thorough evaluation.

Data Mapping Sheet Implementation:

• Leverage a data mapping sheet to simplify database testing, enhancing the verification process for accurate data storage and retrieval.

Column Value Accuracy Check:

• Ensure each column’s values are verified for consistency and accuracy across the database.

Operation Log Validation:

• Test the proper addition of operation logs to confirm that backend activities are recorded correctly and without errors.

Numeric Field Validation:

• Test numeric fields with both positive and negative values to assess the system’s response, identifying whether these inputs are accepted or rejected as intended.

Database Transaction Commitment:

• Verify that all operations correctly commit data to the database, ensuring transaction integrity.

Index Creation and Performance Testing:

• Create and validate database indexes to confirm they enhance performance and meet optimization goals.

Button Functionality Verification:

• Ensure all button and dropdown actions are properly saved and reflected in the database after execution.

Database Design and Field Length Validation:

• Assess the database for proper design, structure, and field lengths, ensuring compliance with the specified requirements.

Stored Procedure Testing:

• Run stored procedures using test data to validate correct execution and expected outcomes.

Primary Key Null Value Handling:

• Verify the handling of null values in primary key columns to ensure data integrity is maintained.

Table Constraints Validation:

• • Ensure all table constraints are functioning correctly, preserving data accuracy and consistency across the database.

The development team is responsible for translating design documents into functional code. They ensure their solution aligns with the architect’s approved design and adhere to best practices throughout the process. Senior developers conduct thorough code reviews to identify and address potential issues, while other team members perform static code analysis to ensure quality.

Given that the project is a banking application with strict security requirements, the team implements robust security checks and audit logging features, prioritizing the safeguarding of sensitive data at every stage of development.
