assert

assert <expr>

或

assert <subCase>, <expr>

• subCase 是一个字符串。若值没有使用引号，也会被解析为字符串。

• expr 是一个布尔值或返回布尔值的表达式。

assert 语句最适合用于单元测试。和注解一起使用可以打印输出测试用例的详细信息。

@testing: case = "inner product 1"
assert [1,2,3]**[4,5,6]==32;
// pass

@testing: case = "inner product 2"
assert [1,2,3]**[4,5,6]==33;
// Testing case inner product 2 failed

@testing: case = "adhocTesting"
assert 1==2;
// Testing case adhocTesting failed

@testing: case = "equal"
assert "one", 1==2
assert "two", 3==4
// Testing case equal_one failed
