+Black box tests for clab
+========================
+
+Clab is a command line address book application.
+It has no interactive features, so black box testing it
+is fairly easy.
+
+Let's start with an empty database.
+
+    SCENARIO empty database
+    GIVEN an empty database
+
+    WHEN listing all records
+    THEN nothing is listed
+
+    WHEN searching for Alice
+    THEN output is empty
+
+    WHEN mutt-querying for Alice
+    THEN no matches
+
+Next, let's add records for Alice and Bob, and make
+sure searches find only the right records.
+
+    SCENARIO database with records
+    GIVEN an empty database
+    AND a record for "Alice Atherton" with e-mail alice@example.com
+    AND a record for "Bob Bobbington" with e-mail bob@example.com
+
+    WHEN listing all records
+    THEN Alice is found
+    AND Bob is found
+
+    WHEN searching for Alice
+    THEN Alice is found
+    AND Bob is not found
+
+    WHEN mutt-querying for Alice
+    THEN Alice is found
+    AND alice@example.com is found
+    AND Bob is not found
+    AND bob@example.com is not found
+
+Implementation
+--------------
+
+These implement the various steps.
+
+    IMPLEMENTS GIVEN an empty database
+    mkdir "$DATADIR/db"
+
+    IMPLEMENTS GIVEN a record for "([^"]+)" with e-mail (.*)
+    cat << EOF > "$DATADIR/db/$MATCH_1.yaml"
+    name: $MATCH_1
+    email: $MATCH_2
+    EOF
+
+    IMPLEMENTS WHEN listing all records
+    ./clab --no-default-config --db "$DATADIR/db" list > "$DATADIR/output"
+
+    IMPLEMENTS WHEN searching for (.*)
+    ./clab --no-default-config --db "$DATADIR/db" find "$MATCH_1" > "$DATADIR/output"
+
+    IMPLEMENTS WHEN mutt-querying for (.*)
+    ./clab --no-default-config --db "$DATADIR/db" mutt-query "$MATCH_1" > "$DATADIR/output" || true
+
+    IMPLEMENTS THEN nothing is listed
+    stat -c %s "$DATADIR/output" | grep -x 0
+
+    IMPLEMENTS THEN output is empty
+    stat -c %s "$DATADIR/output" | grep -x 0
+
+    IMPLEMENTS THEN no matches
+    diff -u "$DATADIR/output" - << EOF
+    No matches
+    EOF
+
+    IMPLEMENTS THEN (.*) is found
+    set -x
+    grep -F "$MATCH_1" "$DATADIR/output"
+
+    IMPLEMENTS THEN (.*) is not found
+    ! grep -F "$MATCH_1" "$DATADIR/output"
