+Subject: [PATCH] Fix tests with Python 3.10
+
+In Python 3, error messages have become a bit more precise. For
+instance, the following code snippet:
+
+----
+class Foo():
+    def bar(self, a):
+        pass
+
+try:
+    Foo().bar(1, 2)
+except TypeError as e:
+    print(e)
+----
+
+will return:
+
+- in Python 3.9: "bar() takes 2 positional arguments but 3 were given"
+- in Python 3.10: "Foo.bar() takes 2 positional arguments but 3 were
+  given"
+
+Fix our tests accordingly.
