Technical Test Analyst: code, load, and reliability

Objectives and progression

Independent CTAL-TTA v4.0 preparation with eight lessons and 53 original decisions on technical quality investigation. Practice statement, decision, and MC/DC coverage, data flow, cyclomatic complexity, memory, workload profiles, recovery, authorization, and architecture review. Fictional APS and banking cases include shared queues, growing memory, incomplete load, visual permissions, connection pools, and intermittent tests. Tools such as gcov, Clang, k6, Playwright, Pact, and PIT illustrate mechanisms and limitations without being exam requirements. The internal assessment has 32 decisions in 60 minutes and reuses course items. The official exam has 45 questions, 78 points, and a 51-point pass in 120 minutes. This course neither reproduces that weighting nor awards certification.

Audience: Technical test analysts, developers, quality professionals, and APS/L3 teams involved in performance, reliability, and releases.

Prerequisites: Testing knowledge, pseudocode reading, and application architecture. CTFL is required for certification; confirm experience criteria and languages with the board or provider.
