TestingXperts and an anonymised fashion and apparel retailer: Integrations test automation case analysed
Verdict: what is checkable
The evidence grade (this site's label for how a case is sourced: primary with client or press confirmation, secondary when vendor-hosted only.) is secondary: the only source is the vendor's own page; of 4 metrics, 0 are verifiable yes, 0 partial and 4 no. [ev-1657]
Client profile as published
- Client
a leading technology-enabled apparel and accessory distributor serving the US and Canadian wholesale markets
(the vendor's description; the vendor does not name the client)- Segment
- Fashion and apparel
- Region
- USA
- Channels
- not stated
- Size indicators
Revenue: $1B+
The client description and size indicators are quoted from the source; segment, region and channels are this site's classification. [ev-1657]
Systems in scope
- Integrations: named in the Challenges and Solution sections (live dependencies, including databases and APIs, and inter-component flows)
Where the source names each system is quoted or summarised from the case page. [ev-1657]
Problem as stated
The distributor was moving code from VB.NET to C# and needed proof that every function behaved the same in both versions. Non-UI files needed exhaustive unit tests. The tests had to run first against the original VB.NET code to set a reference. Real flows with live databases and APIs had to be checked as well as isolated units. [ev-1657]
Even minor discrepancies could disrupt order processing or fulfillment accuracy.(quoted from the source)
Approach
- Testing types
- automation, functional, api and data-migration (main scope: automation)
- Team shape
- not stated
- Duration
- not stated
- Engagement model
- not stated
- Tooling named in the source
- xUnit
Metrics claimed
| Metric | Value | Unit | Claimed by | Verifiable | Evidence |
|---|---|---|---|---|---|
| line code coverage across migrated components | 98%+ | % | vendor | no | ev-1658 |
| functional equivalence validated | 100 | % | vendor | no | ev-1659 |
| manual regression testing time | 30-40 | % | vendor | no | ev-1660 |
| effort for future enhancements and refactoring | 20-30 | % | vendor | no | ev-1661 |
What the case does not say
- Measurement method.
- Duration over which the metric held.
- Team size on both sides.
- Cost.
- Whether the client is still a client.
- Date of the work.
Reading notes for a buyer
This case speaks to the scenario “OMS (order management system: software that routes, splits and tracks customer orders across stores, warehouses and carriers.) or WMS (warehouse management system: software that runs receiving, storage, picking and shipping inside a distribution center.) replacement” and feeds dimension D4 (Test automation evidence) of the methodology. A question to put to TestingXperts:
Does the line coverage figure apply to the non-UI files only or to the whole migrated codebase, and which order processing functions were migrated? [ev-1657]
