示例1: it
it('should support operators', () => {
var lhs = o.variable('lhs');
var rhs = o.variable('rhs');
expect(emitStmt(someVar.cast(o.INT_TYPE).toStmt())).toEqual('(someVar as int);');
expect(emitStmt(o.not(someVar).toStmt())).toEqual('!someVar;');
expect(
emitStmt(someVar.conditional(o.variable('trueCase'), o.variable('falseCase')).toStmt()))
.toEqual('someVar? trueCase: falseCase;');
expect(emitStmt(lhs.equals(rhs).toStmt())).toEqual('(lhs == rhs);');
expect(emitStmt(lhs.notEquals(rhs).toStmt())).toEqual('(lhs != rhs);');
expect(emitStmt(lhs.identical(rhs).toStmt())).toEqual('identical(lhs, rhs);');
expect(emitStmt(lhs.notIdentical(rhs).toStmt())).toEqual('!identical(lhs, rhs);');
expect(emitStmt(lhs.minus(rhs).toStmt())).toEqual('(lhs - rhs);');
expect(emitStmt(lhs.plus(rhs).toStmt())).toEqual('(lhs + rhs);');
expect(emitStmt(lhs.divide(rhs).toStmt())).toEqual('(lhs / rhs);');
expect(emitStmt(lhs.multiply(rhs).toStmt())).toEqual('(lhs * rhs);');
