azkoyen_technical_test
Azkoyen technical test implementation. Implemented (mostly) on standard c++ 17 framework, but with Qt wherever was necessary.
Development approach
A Test-Driven Development (TDD) workflow was followed throughout the project. Every component — from the lowest-level file reader to the GUI window — has a corresponding Google Test suite that was written before (or alongside) the production code. This ensures each module behaves correctly in isolation and makes regressions immediately visible.
SysfsRead class
SysfsReader (include/SysfsRead.hpp, src/core/SysfsRead.cxx) is the lowest-level component. It opens a sysfs-like file and translates its raw text content into a SysfsStatus enum:
| File content | Status |
|---|---|
"1" |
Enabled |
"error: temp too high" |
ErrorTempTooHigh |
| empty / whitespace-only | Empty |
| file missing | Unreachable |
| anything else | UnexpectedValue |
The reader never throws on I/O errors; every outcome is expressed through the enum so callers can react without exception handling. A helper trim_in_place strips trailing whitespace and newlines before comparison.
Tests: tests/test_sysfs_read.cxx — covers all five status branches by writing controlled content to a temporary file.
