This is a 1-function package: `TestEnv.activate()`.
10+
11+
Consider this package has as a test-only dependency of **ChainRulesCore.jl**.
12+
Not a main dependency
13+
14+
```julia
15+
julia> using TestEnv;
16+
17+
julia> TestEnv.activate();
18+
19+
julia> using ChainRulesCore
20+
```
21+
22+
You an also pass in the name of a package, to activate that package and it's test dependencies:
23+
`TestEnv.activate("Javis")` for example would activate Javis.jl's test environment.
24+
25+
Finally you can pass in a function to run in this environment.
26+
```julia
27+
using TestEnv, ReTest
28+
TestEnv.activate("Example") do
29+
retest()
30+
end
31+
```
