Test swift package init (executable)

Create a new package with an executable target.

RUN: rm -rf %t.dir
RUN: mkdir -p %t.dir/Project
RUN: %{swift-package} --package-path %t.dir/Project init --type executable
RUN: rm -rf %t.dir/Project/Sources/*
RUN: echo "print(\"Hello, World!\")" >%t.dir/Project/Sources/main.swift
RUN: %{swift-build} --package-path %t.dir/Project 2>&1 | tee %t.build-log

Check the build log.

RUN: %{FileCheck} --check-prefix CHECK-BUILD-LOG --input-file %t.build-log %s

CHECK-BUILD-LOG: Compiling {{.*}}Project{{.*}}
CHECK-BUILD-LOG: Linking {{.*}}Project

Verify that the tool was built and works.

RUN: test -x %t.dir/Project/.build/debug/Project
RUN: %t.dir/Project/.build/debug/Project > %t.out
RUN: %{FileCheck} --check-prefix CHECK-TOOL-OUTPUT --input-file %t.out %s

CHECK-TOOL-OUTPUT: Hello, World!
