Testing inflation has become one of the main goals in observational cosmology, and one of the scientific priorities for the new generation of Cosmic Microwave Background projects.

A race to more sensitive focal planes, combined to a high control of the instrumental and astrophysical systematic effects, is at play across the globe.

In this talk, I will review some of the current and future observational efforts I am working on, which are all aiming at detecting the inflationary, primordial gravitational waves: POLARBEAR-1, the Simons Array and Simons Observatory, CMB-S4 and LiteBIRD. I will illustrate some of the current challenge that the scientific community has to face, and its plans to overcome them.
