Les Bleues beat the Vietnamese with a wide score of 7-0 on Friday evening to a sold-out crowd at the Stade de la Source in Orléans.
Complete domination and capital control less than a week before the start of the Women's Euro in England.
At the break, France were already leading 6-0 thanks to goals from Delphine Cascarino, Sandie Toletti, Marie-Antonette Katoto, Clara Mateo and a brace from Kadidiatou Diani.
They settled in the Vietnamese camp to play their game against opponents who have never competed.
In the second half, if the pace slowed down somewhat due to the already well-stocked score and the fatigue that set in during the hour of play, the defender and evening captain Aïssatou Tounkara also came from her achievement to score the seventh and last French goal.
Corinne Deacon's players will fly to Great Britain next week, where they will play their first match of the competition against Italy on July 10, in Rotherham.
