ETL Testing

Course Description

This SkillDynamo course develops practical, role-relevant capability in testing ETL and data-integration solutions through source-to-target validation, transformation checks, data quality, incremental loads, performance, automation, migration, and release readiness. The learning path progresses from essential concepts and planning to implementation, validation, troubleshooting, and operational use.

Learners work through realistic scenarios, guided demonstrations, applied exercises, and evidence-based reviews. Every topic is connected to workplace responsibilities, common risks, quality controls, and measurable outcomes.

The course helps professionals make informed decisions, identify failure points, communicate results, and create an actionable improvement plan for future projects.

What You Will Learn

• Define ETL-testing scope, risks, mappings, environments, dependencies, acceptance criteria, traceability, and evidence
• Create representative, boundary, negative, duplicate, missing, invalid, masked, and restart-ready test data
• Validate extraction, transformations, data types, business rules, lookups, joins, aggregations, and target loading
• Reconcile counts, checksums, totals, keys, duplicates, nulls, referential integrity, and exception records
• Test incremental loads, change data capture, late-arriving data, idempotency, reruns, rollback, and recovery
• Measure batch windows, throughput, query behavior, concurrency, resource use, bottlenecks, and service limits
• Automate repeatable validations, produce exception reports, isolate root causes, retest fixes, and preserve evidence
• Assess migration and release readiness with security, audit, reconciliation, monitoring, support, and sign-off controls
