If your vite config is defined as a function, you can define the config like this:
72
+
```ts
73
+
import { defineConfig, mergeConfig } from 'vitest/config'
74
+
import viteConfig from './vite.config'
75
+
76
+
export default defineConfig(configEnv => mergeConfig(
77
+
viteConfig(configEnv),
78
+
defineConfig({
79
+
test: {
80
+
exclude: ['packages/template/*'],
81
+
},
82
+
})
83
+
))
84
+
```
