Testing Infrastructure Methodologies
Client/Server Infrastructure
Servers are essential for various functions, such as website hosting, file management, proxy servers, virtual servers, and supporting physical hardware. The client consists of the operating system, applications, and user settings. Clients utilize the services provided by servers for various functions.
Server/Client components are tested to enhance the efficiency of the infrastructure in a live environment. The testing process involves:
- Assessing the installation/uninstallation of applications.
- Checking browser compatibility.
- Conducting integration tests with various operating system versions and user configurations.
Procedure
- Gather requirements from stakeholders.
- Create a test plan based on the understanding of the needed infrastructure.
- Develop test cases that cover Operating System compatibility, upgrade scenarios, server/client infrastructure testing, and functionality testing.
- Once the test cases are approved, the QA team executes each scenario and its related test cases.
All modifications related to servers and clients, such as upgrades and configuration adjustments, have been thoroughly tested on Quality Assurance setups. Additionally, various operating system versions undergo testing before being implemented in production. In case of any issues during production, fallback procedures have been tested in advance to guarantee reliable backup systems.
Data Migration
Data Migration involves data transfer from an old version to a new version, between servers, and to different configurations. Data Migration testing evaluates data migrations across different versions, servers, and new builds. It’s important to test the application to ensure that the migration does not cause any issues.
Procedure
- Test the application both before and after migration to ensure stability.
- Check the servers before and after data migration to confirm there are no changes.
- Verify that the application’s performance remains consistent post-migration.
- Test the application with various database versions for compatibility.
- Ensure the new build works smoothly across all database versions.
Data migration testing helps identify and address any server-build problems that may arise during the data migration process, ensuring that issues are resolved before deploying the system. This form of testing improves the overall quality and reliability of the product and makes application installation testing smoother in the production environment.
Network-level Testing
The infrastructure of an application relies heavily on the network for communication between servers, clients, and other networks. The network comprises various components like proxy servers and tools for Internet connectivity.
Procedure
- Test the network layer to ensure compatibility with future application updates.
- Check fallback procedures to handle failures in the production environment.
- Perform system testing, user acceptance testing (UAT), and security testing.
- Create test cases and prepare test data.
- Ensure server or network services are not affected by new releases.
- Test the application in an isolated network.
- Evaluate how the application performs on different networks, such as VPN, Wi-Fi, and LAN.
The main goal is to oversee and address network-level challenges such as high resource consumption, server outages, system setup, infrastructure needs for operations, and updates for the Operating System.
Test Environment Infrastructure
A test environment consists of hardware, software, tools, and processes essential for accurate and efficient testing. It provides testers with a suitable workspace equipped with a reliable network, PC, and power supply. This environment is crucial for the successful execution of testing procedures.
The primary goal is to verify the software installation and application configuration settings, select suitable testing tools for test planning and execution, and maintain a consistent flow of test procedures.
