WinkerDu opened a new issue, #2412:
URL: https://github.com/apache/arrow-datafusion/issues/2412
Some unit tests in DataFusion organize expected result string vector in one
line, like `sql::union::union_distinct` do
```
#[tokio::test]
async fn union_distinct() -> Result<()> {
let ctx = SessionContext::new();
let sql = "SELECT 1 as x UNION SELECT 1 as x";
let actual = execute_to_batches(&ctx, sql).await;
let expected = vec!["+---+", "| x |", "+---+", "| 1 |", "+---+"];
assert_batches_eq!(expected, &actual);
Ok(())
}
```
We can separate the expected result string vector into multiple line to make
it more readable and easier to follow, by adding a `#[rustfmt::skip]` tag to
skip fmt check as following code
```
#[tokio::test]
async fn union_distinct() -> Result<()> {
let ctx = SessionContext::new();
let sql = "SELECT 1 as x UNION SELECT 1 as x";
let actual = execute_to_batches(&ctx, sql).await;
#[rustfmt::skip]
let expected = vec![
"+---+",
"| x |",
"+---+",
"| 1 |",
"+---+"
];
assert_batches_eq!(expected, &actual);
Ok(())
}
```
