The all-silicon ATLAS ITk Detector, vertexing and tracking device for the High-Luminosity LHC project, should operate at an ultimate peak instantaneous luminosity up to $7.5\times10^{34}$ cm$^{-2}$ s$^{-1}$ corresponding to approximately 200 inelastic proton-proton interactions per beam crossing. The ITk Strip Detector will consist of four barrel layers and six disks in a forward region on each side of the barrel. They will be composed of individual structures called staves and petals, whose production will require almost 18,000 single-sided strip modules of 8 different designs with the hybrid circuits carrying the front-end microelectronics ASICs glued to the sensor surface. The sensing elements are high resistivity n-in-p silicon strips capable of withstanding fluences up to $1.2\times10^{15}$ n$_{eq}$/cm$^2$. Both irradiated and non-irradiated prototypes of strip modules undergo testing procedures including test beam campaigns supplemented by laser and beta source tests to
check if they meet the design requirements of the detector.
