### Question:
SigningConfigImpl implements SigningConfig, Serializable { @Override public boolean equals(Object o) { if (this == o) { return true; } if (o == null || getClass() != o.getClass()) { return false; } SigningConfigImpl that = (SigningConfigImpl) o; return v1SigningEnabled == that.v1SigningEnabled && v2SigningEnabled == that.v2SigningEnabled && signingReady == that.signingReady && Objects.equals(name, that.name) && Objects.equals(storeFile, that.storeFile) && Objects.equals(storePassword, that.storePassword) && Objects.equals(keyAlias, that.keyAlias) && Objects.equals(keyPassword, that.keyPassword) && Objects.equals(storeType, that.storeType); } private  SigningConfigImpl(
            @NonNull  String name,
            @Nullable File storeFile,
            @Nullable String storePassword,
            @Nullable String keyAlias,
            @Nullable String keyPassword,
            @Nullable String storeType,
            boolean v1SigningEnabled,
            boolean v2SigningEnabled,
            boolean signingReady); @NonNull @Override String getName(); @Nullable @Override File getStoreFile(); @Nullable @Override String getStorePassword(); @Nullable @Override String getKeyAlias(); @Nullable @Override String getKeyPassword(); @Nullable @Override String getStoreType(); @Override boolean isV1SigningEnabled(); @Override boolean isV2SigningEnabled(); @Override boolean isSigningReady(); @Override boolean equals(Object o); @Override int hashCode(); @Override String toString();  }### Answer:
@Test public void equals() throws Exception { EqualsVerifier.forClass(SigningConfigImpl.class).verify(); }
