There is no need for a language or library change; it's literally a one-liner, even in gofmt'ed Go. Just put this one-line func in your tests. https://go.dev/play/p/D60yCWbOuAN Bonus: if you do it my way, the call site is much shorter and requires no external module. |

FWIW we tend to write a generic helper in some packages, like: It is relatively common but I'm not even sure where this would belong in std, other than perhaps builtin, if not the language itself in some other form. |

@mvdan then maybe |
|
see #45624 |
|
also #61082 |
|

I think the generic implementation would be an ideal solution if we could accommodate in language itself as suggested part of std lib, would be easy for almost all go devs :) |

Closing as a dup of #61082. Thanks. |
When we want to pass a string pointer to a struct member each time we have to create a separate variable and pass the address of that to the member variable, Which is a pain. This wrapper function will ease all those efforts.
Eg:
type Employee struct{
Name *string
}
To pass a variable in testing , we have to
testName := "hello"
emp := Employee{
Name: &testName,
}
I have added a pull request to address this as #63299
With this function it is
emp: = Employee{
Name: strings.StringPointerFrom("hello")
}
It is really helpful when we are using table tests.
