Tellimustest

Tellimustest, literally "order test" in Estonian, refers to a set of quality assurance activities that verify the correct processing of customer orders within information systems such as e-commerce platforms, ERP, or order management systems. The aim is to ensure that the order lifecycle operates as intended, including order creation, validation, inventory reservation, payment processing, invoicing, fulfillment, shipping status updates, and returns or cancellations.

Methods commonly used in tellimustest include functional testing of order operations, integration testing with payment services, inventory management, and logistics, as well as performance testing to measure latency and throughput under expected and peak loads. Security testing and regression testing are also important to protect data and ensure that updates do not disrupt existing order flows.

Process typically follows these steps: define test scenarios that reflect real-world use, prepare test data such as customers, products, prices, and stock levels, execute test cases, compare results with expected outcomes, and log defects for remediation. Teams involved often include QA engineers, product owners, developers, and business analysts.

Applications of tellimustest are common in e-commerce, retail ERP, wholesale ordering, and supply-chain platforms. It helps validate business rules such as tax calculation, discount logic, multi-currency handling, and multi-warehouse fulfillment, as well as exception flows like failed payments and returns.
