# Тестирование зависимостей с переопределениями { #testing-dependencies-with-overrides }

## Переопределение зависимостей во время тестирования { #overriding-dependencies-during-testing }

Есть сценарии, когда может понадобиться переопределить зависимость во время тестирования.

Вы не хотите, чтобы исходная зависимость выполнялась (и любые её подзависимости тоже).

Type inference and automatic conversion of values is performed based on the context when the value is un-typed (such as when reading CSV data). If present, the CAST function overrides automatic conversion.

The [mc sql](https://docs.min.io/community/minio-object-store/reference/minio-mc/mc-sql.html) command can be used for executing queries using the command line.

### Set legal hold on an object

PutObject API allows setting legal hold using `x-amz-object-lock-legal-hold` header.

```sh

n := map[int]int{a: f()}      // n may be {2: 3} or {3: 3}: evaluation order between the key and the value is not specified

<p>
At package level, initialization dependencies override the left-to-right rule
for individual initialization expressions, but not for operands within each
expression:

<pre>
var a, b, c = f() + v(), g(), sqr(u()) + v()
