+# General Assertions
+
+* **_AFT.assertEquals(actual, expected)**
+
+ Assert that two values are equal.
+
+ For tables, the comparison is a deep comparison :
+
+ * number of elements must be the same
+ * tables must contain the same keys
+ * each key must contain the same values. The values are also compared recursively with deep comparison.
+
+ LuaUnit provides other table-related assertions, see [Table assertions](http://luaunit.readthedocs.io/en/luaunit_v3_2_1/#assert-table)
+
+* **_AFT.assertNotEquals(actual, expected)**
+
+ Assert that two values are different. The assertion fails if the two values are identical.
+
+ It also uses table deep comparison.
+
+* **_AFT.assertAlmostEquals(actual, expected, margin)**
+
+ Assert that two floating point numbers are almost equal.
+
+ When comparing floating point numbers, strict equality does not work.
+ Computer arithmetic is so that an operation that mathematically yields
+ 1.00000000 might yield 0.999999999999 in lua . That’s why you need an
+ almost equals comparison, where you specify the error margin.
+
+* **_AFT.assertNotAlmostEquals(actual, expected, margin)**
+
+ Assert that two floating point numbers are not almost equal.
