If I run

```julia
a = 15
@test a == 12

```

I get failure and `Evaluated: 15 == 12`

but if I run

```julia
@test isapprox(a, 14.3)

```

I don’t get the evaluated version of `a` which would be nice.

A fix for that is

```julia
@test a ≈ 14.3

```

But doesn’t work for

```julia
@test a ≈ 14.3 atol=1

```
