• Integration Testing: Examines how the application's various components interact with one another.
• End-to-End Testing: Verifies that the application functions as a whole by testing it from beginning to end.
• UI Testing: Verifies that the user interface functions as anticipated.

Development Based on Tests (TDD)

Software is developed using the test-driven restaurants app development company india methodology, in which tests are written before any code is produced. Higher code quality results from ensuring that the code is written to pass the tests.

Ongoing Examination

Automated testing is a procedure that is integrated into continuous development. This keeps the code stable and aids in the early detection of problems.

Advantages

• Reliability: Guarantees that the program functions as planned and is error-free.
• Maintainability: Facilitates code extension and modification without creating new problems.
• Confidence: Offers assurance that the modifications to the code won't affect currently functioning features.

Execution

• Automated Testing Tools: For automated testing, use programs like XCTest, JUnit, and Espresso.
• Continuous Integration: To execute tests automatically, incorporate automated tests into the pipeline for continuous integration.

4. Apply Version Control

Working with other developers and managing codebase changes both depend on version control.

Systems for Version Control

• Git: The most widely used version control system, employed by numerous development teams.
• Mercurial: An additional decentralized VCS.

Ideal Procedures

• Branching Strategy: To handle feature development, bug fixes, and releases, use a branching strategy such as GitFlow or GitHub Flow.
• Commit Statements: To document changes, write concise and informative commit statements.
• Pull Requests: To review and incorporate modifications into the core codebase, use pull requests.

Advantages

• Collaboration: Promotes teamwork and keeps track of coding modifications.
• History: Preserves a history of modifications, facilitating a simple rollback to earlier iterations as necessary.
• Branching: Distinct features or bug fixes can be worked on by developers outside of the main source.

Execution

• Repositories: Create repositories using Bitbucket, GitHub, or GitLab.
• Code Reviews: Make sure that modifications are examined before being merged by using pull requests and code reviews.

5. CI/CD Stands for Continuous Integration and Delivery

Code development, testing, and deployment may all be automated with the help of continuous integration and delivery processes.

Continuous Integration (CI)

Code changes are automatically built and tested as they are pushed to the version control system through continuous integration (CI). This keeps the codebase stable and aids in the early detection of problems.

Ongoing Distribution (CD)

Code updates are automatically pushed to staging or production environments via continuous integration (CD). Faster and more dependable releases are made possible by this.

Advantages

• Automation: Reduces manual labor by automating the build , test, and deployment processes.
• Stability: Maintains the codebase's stability and aids in the early detection of problems.
• Speed: Increases the frequency and dependability of releases.

Execution

• CI/CD Tools: Jenkins, CircleCI, and GitHub Actions are a few examples of CI/CD technologies.
• Automation Scripts: To automate the build, test, and deployment procedures, create scripts.
• Pipelines: Create CI/CD pipelines to automatically execute code modifications through the build, test, and deployment stages.

6. Optimize for Speed

Any mobile app must have excellent performance to succeed. To ensure a positive user experience, performance must be optimized.
