$client = Mockery::mock();
$client->shouldReceive('send')->andThrow($error)->andReturn(true);

不幸的是,它只返回true但不首先抛出异常.如何在第一次调用时抛出异常,然后在方法的第二次调用时返回值?
编辑:
如果我手动编辑Mockery\Expectation.php和设置,这是有效的$_throw
= true.
$client->shouldReceive('send')->twice()->andReturn($error, true);

我这里有两个代码,我只想问两个中哪一个在可写性(编写代码的简易性)和可读性(易于理解代码)方面更好.

我很好奇如果where条件失败,update也会插入值.我读过w3schools,只更新数据库中的现有数据更新,但在我的脚本上,它会自动插入包含数据的行.我想知道它是否可能是脚本中的错误,或者只是UPDATE如何在mysql上运行.
