+# String assertions
+
+Assertions related to string and patterns.
+
+* **_AFT.assertStrContains(str, sub[, useRe])**
+
+    Assert that a string contains the given substring or pattern.
+
+    By default, substring is searched in the string. If useRe is provided and is
+    true, sub is treated as a pattern which is searched inside the string str.
+
+* **_AFT.assertStrIContains(str, sub)**
+
+    Assert that a string contains the given substring, irrespective of the case.
+
+    Not that unlike assertStrcontains(), you can not search for a pattern.
+
+* **_AFT.assertNotStrContains(str, sub, useRe)**
+
+    Assert that a string does not contain a given substring or pattern.
+
+    By default, substring is searched in the string. If useRe is provided and is
+    true, sub is treated as a pattern which is searched inside the string str.
+
+* **_AFT.assertNotStrIContains(str, sub)**
+
+    Assert that a string does not contain the given substring, irrespective of
+    the case.
+
+    Not that unlike assertNotStrcontains(), you can not search for a pattern.
+
+* **_AFT.assertStrMatches(str, pattern[, start[, final]])**
+
+    Assert that a string matches the full pattern pattern.
+
+    If start and final are not provided or are nil, the pattern must match the
+    full string, from start to end. The functions allows to specify the expected
+    start and end position of the pattern in the string.
