The invention provides a branch-integrated quality inspection method, device, electronic equipment and a storage medium, the quality inspection method comprises the steps that merging requests of N branches for merging into an integrated branch are obtained; each branch merges into the integrated branch in the sequence from branch f<0> to f, including after the branch f merges into the integrated branch, the merged integrated branch is operated in a release mode so as to perform quality inspection to the merged integrated branch, and the quality inspection time is K minutes; after thebranch f merges into the integrated branch, the branches from f to f are operated in parallel in a preview mode so as to perform quality inspection to the branches from f to f,and the quality inspection results of the branches from f to f and the quality inspection result of the integrated branch are compared respectively; after the branches from f<0> to f merge into the integrated branch, the quality inspection time of the f<0> is not counted, and the total quality inspection time is 2K(N-1) minutes. According to the provided method and device, the branch merging efficiency is improved.
