ExcoverallsStringConcatenation
=============================
1. `mix deps.get`
2. `MIX_ENV=test mix coveralls.detail | less`
# Actual
Calls to `func` are marked as missed (red) when interpolated in second line of a two line string concatenation `<>`:
```elixir
def call_in_map_value do
%{
key: "one " <>
"#{func}" <>
"three"
}
end
def call_in_unnested do
"one " <>
"#{func}" <>
"three"
end
def second_line_interpolation do
"one " <>
"#{func}"
end
```
# Expected
Calls to `func` are marked as hit (green).
# Other test cases
## Call location
`func` is marked as hit when interpolated in the first line of a two line string concatenation or by itself:
```elixir
def single_line_interpolation do
"#{func}"
end
def first_line_interpolation do
"#{func}" <>
"three"
end
```
## Interpolated value
Expressions that are compile time constants, such as `1 + 1`, are marked as hit:
```elixir
def second_line_constant_interpolation do
"one " <>
"#{1 + 1}"
end
```
