Written by group member Shaznay Lewis along with Peter Hutchings and William Orbit, whilst produced by the latter, it was released as the album's second single on 26 July 2018, by AS Recordings.
Group member Shaznay Lewis commented that "this album feels exactly where we should be - and want to be - right now creatively", and that a highlight was reuniting with "the king of beautiful interesting sounds, William Orbit, which was just amazing".
When asked if they were apprehensive about working with Orbit again and the pressure of having already made two hits with him, Lewis replied: "I know what you mean, but I hate to think that we could never have gone back in the studio with him because we were too scared.
[6] Andre Paine of Evening Standard said that the combination of "steely harmonies and lush electronic textures" was an "appealing throwback" tracks like "After All".
[4] Whilst criticising most of Testament, Laura Snapes of The Guardian commented that "After All is intimate and rueful, with the chorus equivalent of a window being opened on a boiling day – it's a rare moment of genuine emotion".
[9] The accompanying music video for "After All" was directed by Max & Dania, and was premiered on 16 October 2018, on All Saints' official site.
