In the previous article, we have seen few key points of ERP like the real meaning of the term ERP, various modules of ERP, the importance of ERP testing, the criticalities of ERP testing and a road-map for the preparation of the ERP testing.
In this article, let’s get into more practical details on ERP (SAP) Testing like preparing the quality assurance plan, test plan, test suite, test cases and test execution strategy.
This tutorial is a good example for writing test plan from scratch for any application. We have also provided sample test suite template for download.
For the demonstration purpose, let us assume the ERP application under testing consists of the following modules with some key information about the implementation plan as below.

ERP QA Plan
Assuring Quality is a major milestone of any ERP implementation project, which consists of the following stakeholders and success depends on dedicated efforts by all as a “Team”.
The stakeholders of ERP implementation project might be:
- Implementation Team – Consists of the team of professionals from ERP Company or from the local implementation partner. Must have implementation expertise.
- Software Vendor – Software suppliers for the operating system, database and other office applications required for ERP.
- Hosting Provider – Hosting providers for the servers, network, internet and intranet infrastructure required for ERP implementation. Must have implementation expertise.
- Business Team – Consists of the team from the business development or the management steering committee.
- Technical Team – The development team or the implementation team to be available throughout the course of the project. Must have implementation expertise.
- Testing Team – The testing team from the ERP Company or from the local partners having expertise on the ERP implementation strategies.
- Customer Team – The end user team or the departmental heads, who have the complete working knowledge of the business process.
As we discussed in the previous tutorial, testing the ERP (e.g SAP) software application is different than testing the other software applications. ERP applications are domain specific and industry-specific. The common modules like Finance, Accounting, Inventory, Fixed Asset, Sales, Purchase, Human Capital, and Payroll are available in all the ERP systems.
Apart from these common modules, few industrial specific modules are available as per the targeted customers. For example, a “manufacturing ERP” may have a “production planning” module, a “pharma ERP” may have a “doctor-patient” module and an “education ERP” may have a “student” module and so on.
So, the quality factor should be enabled with some pre-defined metrics to be shared well in advance with all the stakeholders in the above list.
To maintain the quality, stakeholders are mutually got into service level agreements. All the stakeholders as a team should have the defined action items, responsibilities with the target dates to achieve the expected quality of statement of work.
ERP Test Plan
ERP test plan should consist of the following information for an effective and successful implementation.
The test plan has the objectives, quality metrics, features to be tested manually, features to be tested through automation tools, project environment, team infrastructure, resource requirements, testing schedule, testing deliverables, test execution infrastructure, testing framework, assumptions, dependencies, constraints, bug tracking mechanism, bug reporting tools and acceptance criteria etc.,
Below is the sample test plan for our ERP implementation project for XYZ Petrochemical LLC.

Confluence and JIRA tools are used for issue tracking in the project. Also, JIRA is customized and configured for all the testing team members to escalate issue and report bugs and assigned to the concern development team with the responsibility and target dates.
ERP Test Suite
Like the normal testing process, ERP Test Suite is normally prepared as an Excel document. This document controls the complete revision history of the various test suites of all the modules in ERP application. The test cases of each module, test execution history, list of bugs and the test report history are maintained in an ERP test suite.
For automation testing, the “test scripts” are maintained in the test suite and the related iteration of test execution history is maintained. Depends on the type of testing and the complexity of the test cases, automation test scripts are maintained in the suite which should be designed in such a way for re-usability.
Find below the snapshot of an ERP test suite in excel document.
Sample Test Suite Template Download:
Below is sample test suite template for download. It contains templates for revision history, test report, bug report, smoke test cases, regression test cases
ERP Test Cases
Apart from the functional test cases, regression test cases, sanity/smoke test cases, ERP Testing requires other type of test cases for installation testing, configuration testing, implementation testing, adaptability testing, network testing, server testing, offline testing, remote testing, multi-currency testing, multi-language testing, device testing, intranet testing, real-time testing etc.,
Most important, ERP being a centralized automated solution, being accessed by multiple users concurrently online in real time, which involves a financial transaction, each and every test cases should be written with a lot of dedicated effort and real-time data.
Also, the test execution status should be updated as “Pass” after verifying the output data with the predefined real-time data. So, the test cases should always have a column for “test data” and “output data”.
Sample Test Scenario:
Find below a sample test case for our ERP demonstration This test cases may consist of a lot of small test cases which can segregate and maintained, but for demo purpose, it’s combined with a single test case.

ERP Testing is having a lot of risks and complexities compared to any software/product testing. Also, managing the quality metrics in ERP implementation projects requires a lot of attention and dedicated efforts as a “team” from the multiple stakeholders.
Testing professionals need to understand the difference between the quality of the product and the quality of implementation. ERP testing requires trusted sponsorship on time and budget from the management and the customers. Testing should be done by the ERP expert team and should not be allocated to an inexperienced team for any reason.
It is very important to use the universally proven right process, methodologies, approaches, and automated tools. We should not assume that “automation” completely replaces the “manual” testing, but should not compromise on using the required testing infrastructure and framework. Don’t underestimate the time required for collecting live real data from the customers.
