PandaTech.Group provides software and system testing services designed for critical safety systems.
The tests include different types of tests subject to the methodologies and methods used in the world of software testing.
Our tests include an in-depth consideration of cyber security issues with a strong emphasis on software immunity.
Testing safety-critical systems is a rigorous process to ensure that software functions reliably and safely. The specific tests required may vary depending on the industry and standards relevant to the system. Here are some common types of tests that Pandatech group typically performs in safety-critical software testing:
Functional Testing
Unit Testing: Tests individual components or modules to ensure they function as expected.
Integration Testing: Ensures that the integrated components work together as intended.
Verification and Validation
Requirements Testing: Ensures that the software meets specified requirements.
Validation Testing: Demonstrates that the system meets the user's needs and intended purpose.
System Testing
System Integration Testing: Verifies that all system components work together.
System Acceptance Testing: Validates that the system meets customer requirements.
Reliability Testing
Reliability and Availability Testing: Ensures the software's reliability and availability under different conditions.
Performance Testing
Load Testing: Evaluates system behavior under normal and peak loads.
Stress Testing: Tests the system's behavior under extreme conditions.
Safety Testing
Hazard Analysis and Risk Assessment: Identifies potential hazards and assesses associated risks.
Failure Mode and Effect Analysis (FMEA): Evaluates the potential failure modes of the system and their impact.
Environmental Testing
Environmental Testing: Assess how the system performs in different environments, including variations in network conditions, hardware configurations, and geographic locations.
Usability Testing
User Interface (UI) Testing: Ensures the usability of the system's interface.
Documentation Testing
Documentation Review: Ensures that all documentation, including manuals and procedures, is accurate and complete.
Change Management and Configuration Testing
Configuration Management Testing Verifies that changes to the software configuration do not adversely affect system functionality.
Fault Tolerance and Recovery Testing
Fault Injection Testing: Simulates faults to assess the system's ability to recover.
Design verification & validation
This testing phase aims to verify that the design of the software is reliable and aligned with the specified requirements before moving on to the implementation phase.
Regulatory Compliance Testing
Ensures that the software complies with relevant safety standards and regulations.
Security Testing
Penetration Testing: Identifies vulnerabilities in the system's security.
Security Audits: Reviews the system's security mechanisms and policies.
Compliance Testing
Compliance Testing: Verify that the system adheres to industry-specific regulations and standards, such as GDPR, HIPAA, or ISO 27001.
Cryptographic Testing
Cryptographic Testing: Assess the strength and effectiveness of cryptographic implementations, including encryption algorithms and key management processes.
API Security Testing
API Security Testing: Focus on the security of APIs and their interactions between different systems. Check for proper authentication, authorization, and data validation.
Threat Modeling
Threat Modeling: Identify and evaluate potential threats and vulnerabilities in the system's architecture early in the development process. This can help in designing security controls and countermeasures.
Supply Chain Security Testing
Supply Chain Security Testing: Evaluate the security of third-party components, libraries, and dependencies to ensure they do not introduce vulnerabilities into the system.
Identification of Vulnerabilities
The main objective is to identify and document potential security vulnerabilities that could be exploited by malicious actors. This may include weaknesses in software, network infrastructure, human factors, or a combination of these.
It's important to note that in safety-critical systems, compliance with industry-specific standards such as ISO 26262 (automotive), DO-178C (aerospace), or IEC 61508 (industrial) is often mandatory. Tailor your testing approach to meet the specific requirements of these standards and the safety integrity level (SIL) of your system. Additionally, collaboration with domain experts, thorough documentation, and traceability are critical aspects of the testing process in safety-critical systems.
