Podcast Episode: Testing Enterprise Software

In this episode, I talk to Ursula Beiersdorf about the challenges and methods of testing in large enterprise environments, especially in the context of SAP and other configurable systems. Ursula shares her experiences and highlights the importance of understanding the complexity of such systems. She talks about integrating test criteria into user stories, using process modeling and promoting test automation. She also shows how crucial the involvement of different stakeholders and experience-based testing techniques are for the success of testing.

"What I've noticed is that many people don't take configuration seriously, even though it can have very nasty side effects." - Ursula Beiersdorf

Ursula Beiersdorf realized the importance of good quality in software development in her first project more than 30 years ago after studying business mathematics. Since then, she has worked for several decades as a test consultant, mainly for major customers. Parallel to this work, she discovered the Hamburg software testing community StugHH, of which she soon became a moderator. In more than 12 years, together with the other Hamburg quality obsessives, she has created an opportunity for learning and exchange. A few years ago, she took on the challenge of transferring her testing knowledge to the SAP sector. Among other things, this resulted in the podcast "Testschnack", the first German podcast about exciting questions in the testing of highly integrated systems of systems such as SAP.

Three years ago, she switched sides to a manufacturer of forklift trucks in order to make the test fit for upcoming changes as an internal test service manager, especially for enterprise software.

Enterprise Software Testing

Introduction to testing enterprise software

Enterprise software testing plays a crucial role in large organizations. It ensures that complex systems such as SAP function properly and meet user requirements.

Important aspects of enterprise software testing

1. Importance of testing: Ensuring the quality and reliability of software solutions

• **Challenges in enterprise testing:**High complexity due to numerous interfaces
• Need to adapt to specific business requirements
• Unexpected side effects due to configurations

These challenges require a comprehensive strategy and specialized knowledge to achieve the desired results. Such a strategy could include the implementation of effective test management, which includes objectives, planning and risk-based testing for successful software development.

The basics of enterprise testing

Enterprise Testing refers to the test process of purchased systems, especially those that are heavily customized. An example of this is SAP, a widely used ERP system in large companies. In this context, customization plays a crucial role; it enables companies to meet specific requirements, but can also increase the complexity and challenges of testing.

Testers have a central function in this environment. They are often users with in-depth business knowledge, which enables them to evaluate the system from the end user's perspective. At the same time, there is often a lack of specialized testing tools and methods to effectively guarantee the quality of the customizations.

Testers have to deal with various aspects:

• Understanding the system configurations
• Identifying possible sources of error
• Ensuring an effective test process despite insufficient resources

These elements are essential for the success of enterprise testing and demonstrate the need for a structured approach combined with in-depth expertise.

Complexity and challenges in enterprise testing

The complexity of enterprise testing is often compounded by collaboration and interfaces with systems such as SAP. These systems tend to be highly configured and require careful coordination between different departments and teams. Here are some key challenges:

• Collaboration: Interdisciplinary collaboration between developers, testers and business users is crucial. Misunderstandings can lead to errors in testing.
• Interfaces: The integration of SAP with other systems can cause unexpected problems. Interfaces must be clearly defined and tested to ensure that all systems work together seamlessly.

Unexpected side effects of configurations are a common problem. Changes to one part of the system can have unforeseen effects on other parts. Often these side effects go undetected with insufficient testing, leading to potential risks to business operations.

An example of an area that requires special attention is Data Warehouse Testing. Here, optimal test strategies need to be developed to understand the specific challenges and methods for effective results verification.

The challenge is to develop a comprehensive test strategy that takes all these complexities into account. Structured testing is necessary to understand the impact of configurations and to ensure that all aspects of the system are working properly.

The role of testers in enterprise testing

The requirements for testers in enterprise testing are high. Testers not only need technical knowledge, but also enterprise knowledge. This enables them to understand the specific processes and needs of the organization and to respond effectively to its requirements.

Challenges for testers in enterprise testing

A common problem is the lack of suitable testing tools. Many testers work with limited resources and often have to improvise. The availability of specialized tools could significantly increase efficiency, but there is often a lack of training programs to use these tools effectively.

Methods for training testers

Various methods are required to train smaller testers:

• Practical workshops: Interactive sessions where testers share experiences and learn from real-life scenarios.
• Abstract examples: Use of hypothetical scenarios or simulated projects to make complex concepts understandable.

A structured approach to training can help deepen understanding of testing methods and ensure that testers are prepared for any challenges. Integrating business knowledge into the test process not only improves the quality of testing, but also encourages collaboration between teams.

Test methods and designs in an enterprise context

In enterprise testing, various testing methods are used that are tailored to the specific requirements of large companies. The most common methods include

• Integration testing: Appraisal of whether different systems and components work together smoothly.
• User story testing: Focus on specific requirements from the end user's perspective.
• End-to-end testing: Simulate the entire business process from start to finish.

The multitude of business requirements can lead to a significant overload of testers. This situation arises when testers try to perform a large number of tests in a short period of time in order to meet the growing business demands. The consequences of this overload are manifold:

• Reduced test quality: Speed can lead to inadequate testing, causing critical defects to be overlooked.
• Stress and frustration among testers: High pressure has a negative effect on the motivation and efficiency of testers.

Implementing structured testing methods, such as system testing, is crucial to ensure a balance between the organization's requirements and the quality of the test results. For example, system testing checks whether the software meets all requirements and provides a comprehensive view of the quality of the overall system.

Adapting processes to improve efficiency in the testing process should be a priority. The test levels provide structure for tests and help to test different areas of the software in a targeted manner.

Types of testing in an enterprise context

Two main types of testing are crucial in enterprise testing: user story testing and integrative testing. This distinction has a significant impact on the entire testing process.

User story testing

User story testing focuses on small, specific requirements derived directly from end user needs. They enable a quick appraisal of individual functionalities and help to integrate user feedback at an early stage.

Integrative tests

Integrative tests, on the other hand, cover larger contexts and check how different components of a system work together. These tests are more complex as they often involve several systems or modules and must ensure that all parts interact harmoniously.

The importance of these two test types lies in their ability to shed light on different aspects of software quality. While user story tests support agile customization, integrative tests ensure the stability and functionality of the entire system.

Another aspect is optimization through pipelines during testing. With optimized pipelines, teams can automate their test processes and make them more efficient. This leads to faster feedback for developers and enables a more agile response to changes in the course of the project. Pipeline optimizations not only reduce manual effort, but also increase test coverage and quality.

Change management and persuasion in enterprise testing

Change management plays a decisive role in the success of testing in companies, especially when introducing and adapting enterprise software. Organizational change requires a thoughtful approach to ensure that all stakeholders understand the need for and benefits of test processes.

Key strategies for convincing stakeholders include:

• Transparent communication: Clear information about the test process and its importance to the organization is essential. Stakeholders should recognize the risks associated with inadequate testing.
• Training and workshops: Targeted training opportunities raise awareness of the importance of testing. Practical examples help to illustrate the benefits in concrete terms.
• Participation in decision-making processes: Actively involving stakeholders in the test process promotes understanding and acceptance. This creates trust and reduces resistance to change.
• Share success stories: Concrete positive results from previous projects can be used to support arguments. These examples show how effective testing leads to an improvement in software quality.

Implementing these strategies can be critical to fostering a positive attitude towards enterprise software testing and increasing process effectiveness.

Tools for enterprise testing

The selection and use of appropriate tools plays a crucial role in enterprise testing. One of the preferred tools is Excel, which is often used due to its familiarity and ease of use. The advantages of Excel include:

• User friendliness: Many testers are already familiar with Excel.
• Flexibility: Customization and specific queries can be easily implemented.

However, there are also disadvantages:

• Limited automation: Manual input can be prone to errors.
• Scalability: Excel can quickly become confusing for large projects.

An innovative addition in this context is X-Ray, a tool developed specifically to improve defect management. X-Ray integrates seamlessly into JIRA and offers the following advantages:

• Effective defect tracking: Users can track and manage defects in detail.
• Test coverage: X-Ray allows visualization of test coverage per user story, which supports quality assurance.

With these tools, the entire testing process is optimized, allowing testers to work more efficiently. The combination of Excel for simple tasks and X-Ray for complex defect management shows how important the right tool selection is in enterprise testing.

Defect management in enterprise testing

In enterprise testing, defect categorization plays a central role in the traceability and effective management of defects. Defects are typically divided into four categories:

• Permissions: Issues related to authorizations and access rights.
• Functional testing: Defects that occur during the appraisal of specific functions.
• Integration errors: Difficulties that come to light when integrating different systems or components.

This categorization enables testers to work specifically on the identified weaknesses and develop prioritized solutions.

The retro-evaluation is another important aspect of defect management. It offers teams the opportunity to learn from past projects. By analyzing defects that have occurred, valuable insights can be gained to optimize future test processes.

Key points that should be considered during retro-evaluation:

• Identification of recurring sources of defects
• Evaluation of the effectiveness of already implemented solutions
• Adaptation of test strategies based on the knowledge gained

A structured approach to defect management not only promotes the quality of the tests, but also strengthens trust between the stakeholders and the tester team.

The role of AI in the test process

The integration of artificial intelligence (AI) into the test process of enterprise software plays a crucial role in improving the efficiency and quality of testing. By using AI, companies can:

• assess defects: AI-powered algorithms analyze test results to identify patterns and assess the severity of defects. This enables targeted prioritization of defect fixes.
• Identify sources of defects: AI can help find the root causes of defects faster by analyzing historical test data and identifying potential problem areas. This ability to identify source of error reduces the time testers spend troubleshooting.

The use of AI in AI lectures demonstrates how these technologies can revolutionize testing. Companies benefit not only from faster test results, but also from higher accuracy in error analysis.

The use of structured processes for error assessment and identification not only increases testing efficiency, but also strengthens confidence in the tested systems. The challenges in enterprise testing require innovative solutions, and AI is proving to be a valuable tool for successfully overcoming these challenges.

SAP-specific testing

The SAP test approaches differ significantly from individual development processes. The focus on modular systems at SAP brings specific challenges.

1. Modular structure

SAP systems consist of different modules that need to work together seamlessly. Each module has its own functions and configurations, which makes test coverage complex.

2. Test technique

While individual approaches often require customized solutions, SAP testing uses predefined standards and best practices to account for modularity.

3. Configuration management

Changes to one module can have unexpected effects on other modules. These interactions must be carefully considered during testing.

A deep understanding of these differences is crucial for effective SAP-specific testing. The need to perform extensive testing requires a structured approach to the validation of changes in these modular systems.

Structured testing for configuration changes

Performing structured testing is essential, especially for configuration changes in SAP systems. These tests ensure that all changes are comprehensively appraised and that no unexpected side effects occur. A deep process understanding is necessary to understand the impact of changes on business processes.

Important aspects:

• Risk identification: Identification of potential problems that may result from configurations.
• Test coverage: Ensuring that all relevant scenarios are covered.
• Documentation: Tracking changes and their impact to improve future testing.

Structured testing ensures that customizations not only work technically, but also meet business requirements. This helps to significantly increase the quality of Testing of Enterprise Software and create confidence in system integrity.
