# shellcheck shell=sh

# Each block (example group / example) runs within subshell.
# It means that it works like lexical scope.

Describe 'scope example'
foo() { echo "foo"; } # It can call from anywhere within this example group

# By the way, you can only use shellspec DSL or define function here.
# Of course it is possible to write freely within the defined function
# but other code may breaks isolation of tests.

It 'calls "foo"'
When call foo
The output should eq 'foo'
End

It 'defines "bar" function'
bar() { echo "bar"; }
When call bar
The output should eq 'bar'
End

It 'cannot call "bar" function, because different scope'
When call bar
The status should be failure # probably status is 127
The stderr should be present # probably stderr is "bar: not found"
End

It 'redefines "foo" function'
foo() { echo "FOO"; }
When call foo
The output should eq 'FOO'
End

It 'calls "foo" function of outer scope (not previous example)'
When call foo
The output should eq 'foo'
End

Describe 'sub block'
foo() { echo "Foo"; }

It 'calls "foo" function of upper scope'
When call foo
The output should eq 'Foo'
End
