Cloud Functionsのテスト導入中

CloudFunctionsテスト導入。

このエラーが出る。

tsconfig見てない？試しに__test__直下にtsconfig置いて、compilerOptionsを親のものをコピペしてみる。

nextが呼ばれてしまうので、nextの設定がいろいろないとテストが実行されなそう。 functionsごとに別ファイルで切り出して、next以外の関数だけimportする。

更にハマる。またこれ。

こうじゃなくて

import functionsTest from 'firebase-functions-test'

これでよかった

import * as functionsTest from 'firebase-functions-test'

前はlintエラーだったのに起きなくなった。

そしてこれ。え？まじか。

Cannot encode [object Object]to a Firestore Value. Local testing does not yet support Firestore geo points.

オブジェクトの構造だけ合わせる。

-          geo: new admin.firestore.GeoPoint(35.635557, 139.786987),
+          geo: {
+            _latitude: 35.635557,
+            _longitude: 139.786987,
+          },

あとはalgoliasearchをモックできれば動きそうな気配。
